Parties the Founders Distrusted
The Constitution never formally addressed political parties. George Washington and other Founders feared organized factions would produce conflict and paralysis. Yet parties emerged almost immediately as Americans debated the proper direction of the new republic.
Alexander Hamilton’s followers favored a strong central government supporting commerce and industry. Thomas Jefferson’s allies preferred a decentralized agrarian republic. These early factions became the first party system.
Parties Rise and Fall
The Federalists disappeared, while the Democratic-Republicans evolved into the Democrats led by Andrew Jackson. The Whigs later replaced the National Republicans, but collapsed over the question of whether slavery should expand into western territories. The Republican Party emerged in the 1850s opposing slavery’s expansion and soon carried Abraham Lincoln to the presidency.
Since 1852, Democrats and Republicans have won every presidential election, and they have controlled Congress since at least 1856.
The Electoral Trap
The system reinforces this dominance. Most elections use single-member districts in which the candidate with the most votes wins, even without a majority. This first-past-the-post system makes smaller parties appear unlikely to win, encouraging voters to support one of the two leading candidates rather than risk splitting the vote.
State ballot-access rules can make the challenge still harder, requiring minor parties to gather many petition signatures in limited periods.
Two Coalitions, Many Factions
America’s parties are not tightly controlled national organizations. Primaries often determine nominees, and elected officials can defy party positions. Each party contains competing factions and changes over time.
The two-party system is therefore not proof of political unity. It is a structure that compresses a country’s many arguments into two enormous, constantly shifting coalitions.
