Voting and Elections

Elections are the central mechanism through which Americans choose their leaders and influence policy. The United States holds elections at every level — federal, state, local — making it one of the most election-saturated democracies in the world. Yet turnout is comparatively low, and the rules governing elections vary widely across states.

Who Can Vote

The Constitution originally left voting eligibility to states, which generally restricted it to white, male, property-owning Christians. Federal expansion has come through constitutional amendments and statutes:

  • 15th Amendment (1870): cannot deny the vote on account of race.
  • 17th Amendment (1913): direct election of senators.
  • 19th Amendment (1920): cannot deny the vote on account of sex.
  • 24th Amendment (1964): banned poll taxes in federal elections.
  • Voting Rights Act of 1965: banned literacy tests; required federal preclearance for election-law changes in jurisdictions with discrimination histories.
  • 26th Amendment (1971): voting age set at 18.

Today, all U.S. citizens 18 and older have the constitutional right to vote, with limited exceptions for some states' laws on people with felony convictions.

Voter Turnout

  • Presidential elections: roughly 60% of eligible voters turn out (66% in 2020, the highest in over a century).
  • Midterm elections: about 40%.
  • State and local elections: often less than 25%.
  • U.S. turnout LAGS most other established democracies that have parliamentary systems with proportional representation, automatic registration, and weekend or holiday voting.

Predictors of Voter Turnout

  • Education — strongest predictor; college graduates vote at much higher rates than non-graduates.
  • Age — older voters turn out more reliably; young voters chronically under-vote.
  • Income — higher-income voters turn out more.
  • Race — turnout gaps have narrowed but persist; white turnout exceeds Black turnout exceeds Hispanic and Asian turnout in most cycles.
  • Civic engagement — union members, churchgoers, and members of organizations vote more.
  • Salience — close races and high-stakes issues drive turnout.

Election Types

  • Primary elections — voters within a party choose the party's nominee. Closed primaries (only registered party members can vote), open (any voter can choose either party's primary), or semi-closed variants. Primaries amplify the influence of partisan, ideologically extreme voters.
  • Caucuses — meetings of party members to choose nominees. Mostly replaced by primaries; Iowa famously kept caucuses for decades.
  • General elections — voters across parties choose between major-party nominees and (sometimes) minor-party candidates.
  • Special elections — to fill mid-term vacancies.
  • Ballot initiatives and referendums — direct democracy at the state and local level.

The Electoral College

Article II created the Electoral College as the constitutional mechanism for electing the president:

  • Each state has electors equal to its House delegation + 2 senators (plus 3 for D.C. via the 23rd Amendment).
  • A candidate needs 270 of 538 electoral votes to win.
  • Most states (48 + D.C.) use winner-take-all allocation. Maine and Nebraska use the congressional district method.
  • If no candidate gets 270, the House decides (each state delegation gets one vote).
  • The Electoral College CAN produce a winner who lost the national popular vote (1824, 1876, 1888, 2000, 2016).

Voting Rules and Recent Battles

States control most voting rules, leading to wide variation:

  • Voter ID laws — supporters argue they prevent fraud; critics argue they suppress turnout among low-income, minority, and elderly voters who are less likely to have IDs.
  • Mail and early voting — expanded dramatically in 2020 due to COVID; partially rolled back since.
  • Felon disenfranchisement — varies sharply by state (Maine and Vermont allow voting from prison; Florida required a constitutional amendment in 2018 to restore felon voting rights).
  • Same-day registration / automatic registration — adopted by some states to expand turnout; rejected by others.

Shelby County v. Holder (2013) and Voting Rights

Struck down the preclearance formula of Section 4(b) of the Voting Rights Act, effectively gutting Section 5 (which had required Justice Department preclearance for election-law changes in covered jurisdictions). After Shelby, several states with histories of discrimination passed strict voter ID laws, purged voter rolls, and closed polling places — practices civil-rights groups argue have suppressed minority votes.

Why It Matters

Elections — and the rules governing them — determine who holds power. Small changes in turnout, registration, district lines, and voter eligibility can swing close elections and decisively shape policy outcomes for millions.

📚 Practice Problems

1Problem 1easy

❓ Question:

Identify THREE constitutional amendments that expanded voting rights and explain what each did.

💡 Show Solution
  1. 15th Amendment (1870): Prohibits denying the vote on account of "race, color, or previous condition of servitude." Was widely circumvented in the South for nearly a century through poll taxes, literacy tests, white primaries, and intimidation; finally enforced effectively only after the Voting Rights Act of 1965.

  2. 19th Amendment (1920): Prohibits denying the vote on account of sex — gave women the constitutional right to vote nationwide. Culmination of nearly a century of suffrage activism (Seneca Falls, 1848 → 19th Amendment, 1920).

  3. 24th Amendment (1964): Banned poll taxes in federal elections. Followed by Harper v. Virginia Board of Elections (1966), which extended the ban to state elections.

  4. 26th Amendment (1971): Set the voting age at 18, in response to demands during the Vietnam War that those drafted to fight should also be eligible to vote.

(Also valid: 17th Amendment (1913) on direct election of senators; 23rd Amendment (1961) gave D.C. residents electoral votes.)

2Problem 2easy

❓ Question:

What is the Electoral College, and how many electoral votes does a candidate need to win the presidency?

💡 Show Solution

The Electoral College is the constitutional mechanism for electing the President of the United States, established by Article II of the Constitution. Each state is allocated electors equal to its House delegation plus two senators (so a state like California has 54 electors — 52 House seats + 2 senators; Wyoming has 3 — 1 House seat + 2 senators). The 23rd Amendment (1961) gives Washington, D.C. 3 electors.

Total electors: 538 (435 House + 100 Senate + 3 D.C.).

A candidate needs a MAJORITY = 270 electoral votes to win the presidency.

Most states (48 + D.C.) use winner-take-all allocation: the candidate winning the state's popular vote gets all of the state's electors. Maine and Nebraska use the congressional district method (one elector per congressional district plus two for the statewide winner), making it possible to split a state's electors.

If no candidate reaches 270, the House of Representatives chooses the president, with each state delegation casting ONE vote — a procedure used twice (1800 and 1824) and a contingency that is occasionally raised but unlikely under modern conditions.

Because of the winner-take-all rule and population distribution, the Electoral College CAN produce a winner who lost the national popular vote — happened in 1824, 1876, 1888, 2000 (Bush), and 2016 (Trump).

3Problem 3medium

❓ Question:

Explain why voter turnout in the United States is lower than in most other established democracies. Give THREE structural or cultural reasons.

💡 Show Solution
  1. Elections are held on Tuesdays and are not federal holidays. Most other democracies vote on weekends or declare a national holiday. American workers must take time off, find childcare, and travel to polling places — barriers that disproportionately affect low-income workers without flexible schedules.

  2. Voters are responsible for registering, often well in advance. Most other established democracies have AUTOMATIC voter registration (the government registers all eligible adults). U.S. registration deadlines (sometimes 30 days before an election) and inconsistent online procedures depress turnout, particularly among young, low-income, and mobile voters.

  3. Frequent and complex elections. Americans face elections every year for many offices and ballot questions; the resulting cognitive burden and "voter fatigue" depresses turnout, especially for non-presidential races.

  4. Single-member, winner-take-all districts mean many voters in non-competitive districts feel their vote does not count. Proportional representation systems give every vote weight in the legislature, increasing turnout.

  5. Lower party mobilization in safe districts. Political parties focus mobilization in swing states/districts, leaving voters in safe areas less contacted.

  6. Voter ID laws and polling-place closures in some states impose extra costs on voting (especially for minority and low-income voters).

  7. Cultural disengagement. Lower civic education, less union membership, and more political cynicism reduce participation.

(Other valid factors: felon disenfranchisement, mail-voting restrictions, gerrymandered districts.)

4Problem 4medium

❓ Question:

Compare closed and open primary elections. What are the advantages and disadvantages of each system?

💡 Show Solution

Closed primary: Only voters who are REGISTERED MEMBERS of a party can vote in that party's primary. Independents and members of other parties are excluded.

Open primary: ANY registered voter may choose which party's primary to vote in (typically can vote in only one party's primary in a given election). No party affiliation required.

(Semi-closed and other variants exist — independents allowed in but not members of opposing parties.)

Advantages of closed primaries:

  • Party control. Parties can ensure only committed members choose their nominees, preventing outsiders from picking weak candidates or "raiding" to nominate someone unelectable.
  • Coherent party brand. Nominees tend to reflect party priorities more accurately.
  • Stronger party loyalty. Closed primaries can encourage voters to formally affiliate with a party.

Disadvantages of closed primaries:

  • Excludes independents. Roughly 40% of American voters identify as independents and cannot participate in nominating contests, reducing democratic input.
  • Empowers more ideologically extreme primary voters. Closed-primary voters tend to be more partisan and ideological than the general electorate, pulling nominees away from the median voter.
  • Can produce nominees who are too extreme to win general elections.

Advantages of open primaries:

  • Includes more voters, especially independents.
  • May produce more moderate nominees who appeal to a broader cross-section of the electorate.
  • More democratic in a small-d sense — fewer barriers to participation.

Disadvantages of open primaries:

  • Strategic voting / "raiding." Voters from one party can cross over to vote in the other party's primary, potentially nominating a weak candidate (e.g., "Operation Chaos" calls in 2008 from Limbaugh to Republican voters to vote in Democratic primaries).
  • Weakens party identity and discipline.
  • Can produce nominees who do not represent the party's core members.

Real-world note: California and Washington use a non-partisan top-two primary — all candidates from all parties run on a single ballot, and the top two finishers (regardless of party) advance to the general election. Designed to produce more moderate nominees; produces same-party general elections in safe districts.

5Problem 5hard

❓ Question:

Shelby County v. Holder (2013) struck down the preclearance formula of the Voting Rights Act. (a) Explain what preclearance was and which provision of the VRA established it. (b) Why did the Court strike it down? (c) What has been the practical effect on voting laws in the United States since 2013?

💡 Show Solution

(a) Preclearance required that certain state and local jurisdictions — those with documented histories of voting discrimination — submit any change in voting laws or procedures (new voter ID laws, polling-place changes, redistricting maps) to the U.S. Department of Justice or the U.S. District Court for D.C. for advance approval BEFORE the change could take effect. Established in Section 5 of the Voting Rights Act of 1965, with the COVERAGE FORMULA (which jurisdictions were subject to preclearance) in Section 4(b). Approximately nine states (mostly Southern) and parts of others were covered.

(b) Why the Court struck it down (Roberts, 5–4): The majority held that the Section 4(b) coverage formula was UNCONSTITUTIONAL because it relied on data from the 1960s and 1970s — racial discrimination patterns from decades earlier — without sufficient updating. Roberts argued that "things have changed in the South" and that Congress could not impose preclearance based on outdated assumptions about which jurisdictions still discriminated. The Court did not strike down Section 5 itself but, because Section 5 has no operative coverage formula, it became effectively dormant. Congress has not passed an updated formula despite proposed legislation (John Lewis Voting Rights Advancement Act).

The dissent (Ginsburg) argued the majority had ignored extensive evidence Congress had compiled in 2006 of CONTINUING discrimination in covered jurisdictions and that "throwing out preclearance when it has worked and is continuing to work to stop discriminatory changes is like throwing away your umbrella in a rainstorm because you are not getting wet."

(c) Practical effects since 2013:

  1. Strict voter ID laws in covered states (Texas, North Carolina, Georgia, Alabama) — some struck down by federal courts, others survived. North Carolina's 2013 law was struck down by the Fourth Circuit as targeting Black voters "with almost surgical precision."

  2. Polling-place closures. Hundreds of polling places have closed in covered jurisdictions, often disproportionately in minority neighborhoods. The Leadership Conference on Civil Rights documented over 1,600 polling places closed between 2012 and 2018 in formerly covered states.

  3. Voter roll purges. Several covered states implemented aggressive purging of inactive voters (Ohio's "supplemental process" upheld in Husted v. APRI, 2018; Georgia's "exact match" laws).

  4. Congressional redistricting in covered states proceeded without preclearance review; courts have struck down some maps as racial gerrymanders.

  5. Increased burden on individual litigants. Section 2 of the VRA still allows lawsuits AFTER the fact, but plaintiffs must prove discriminatory intent or effect — far slower and more expensive than preclearance.

The political fight over voting rights has shifted to state legislatures, state courts, and Congress. Federal legislation (Freedom to Vote Act, John Lewis Act) has been blocked by Senate filibuster. Roberts's prediction that "things have changed in the South" has been contested by post-2013 voting-rights litigation showing many of the same discriminatory patterns the VRA was designed to address.
