Elections, parties & political behavior
How Americans elect their leaders: the Electoral College, the two-party system, primaries, campaign finance law, and the drivers of voter behavior—FSOT core.
The Electoral College and the Mechanics of Federal Elections
The President is not chosen by national popular vote. Article II, Section 1 and the Twelfth Amendment (1804) vest selection in the Electoral College, which since the Apportionment Act framework comprises 538 electors: one per Representative (435) and Senator (100), plus three for the District of Columbia under the Twenty-third Amendment (1961). A candidate needs an absolute majority of 270. If no candidate reaches 270, the House chooses the President voting by state delegation (one vote each), the procedure last invoked in the contingent election of 1824, which seated John Quincy Adams over Andrew Jackson despite Jackson's plurality.
Forty-eight states and D.C. award electors winner-take-all; Maine and Nebraska use the congressional-district method. The system produced popular-vote losers winning the presidency in 1824, 1876, 1888, 2000, and 2016. In Bush v. Gore (2000) the Supreme Court halted the Florida recount on Equal Protection grounds, effectively awarding the state—and the presidency—to George W. Bush. In Chiafalo v. Washington (2020) the Court upheld state "faithless elector" laws, confirming states may bind electors to the popular vote.
Apportionment, Redistricting, and the Franchise
The decennial census drives reapportionment of House seats among states; states then draw district lines. The Supreme Court established one person, one vote in Baker v. Carr (1962) and Reynolds v. Sims (1964), requiring roughly equal district populations. Racial gerrymandering is justiciable (Shaw v. Reno, 1993), but in Rucho v. Common Cause (2019) the Court held partisan gerrymandering a nonjusticiable political question in federal courts.
The franchise expanded through the Fifteenth (1870), Nineteenth (1920), Twenty-fourth (1964, banning poll taxes), and Twenty-sixth (1971, voting age 18) Amendments and the Voting Rights Act of 1965. Shelby County v. Holder (2013) struck down the VRA's Section 4(b) coverage formula, ending federal preclearance of voting-law changes in covered jurisdictions and triggering a wave of state voter-ID and access laws.
Primaries, Conventions, and the Party Nomination
Nominations run through state primaries and caucuses, not the Constitution. The modern primary-dominant system dates to post-1968 reforms (the McGovern–Fraser Commission) after the contentious 1968 Democratic Convention. Iowa's caucuses and New Hampshire's primary traditionally open the calendar; "Super Tuesday" clusters many contests. National conventions formally nominate the ticket and ratify the platform, but since the 1970s they largely confirm a winner already determined by pledged delegates. Understanding this sequence—primary, convention, general election, Electoral College certification on January 6 under the Electoral Count Reform Act of 2022—is essential FSOT terrain.
