U.S. Senate
Representation and size
The House has 435 members elected from population-based districts, making it responsive to demographic shifts. The Senate has 100 members — two per state regardless of population — giving Wyoming (580,000 people) equal representation to California (39 million).
Electoral cycles and accountability
House members serve two-year terms, keeping them in near-permanent campaign mode and closely tied to constituent opinion. Senators serve six-year terms with staggered elections, designed to insulate them from short-term political pressure and encourage longer-term thinking.
Institutional rules and culture
The House operates under strict majority rule with limited debate time, controlled by the Speaker and Rules Committee. The Senate has the filibuster, unlimited debate tradition, and individual holds — giving minority members and even single senators far more procedural power to block or delay action.
Unique powers
The House has the exclusive power to initiate revenue legislation and impeach federal officials. The Senate has the exclusive power to confirm presidential appointments, ratify treaties, and try impeachments. These distinct powers give each chamber different strategic importance depending on the political moment.
