# 1910 Midterm Elections [[William Howard Taft]] administration midterm. Democrats took the House for the first time since 1892 — a massive 56-seat gain. The triggering events were the unpopular **Payne-Aldrich Tariff** of 1909 (raised rates rather than lowering them as Republicans had promised), the **"Cannon Revolt"** of March 1910 (Progressive Republicans + Democrats stripped Speaker Joseph Cannon of dictatorial Rules Committee control), and broader Taft-Roosevelt fracture over conservation, antitrust, and progressive reform. ## Result - **House:** Democrats gained ~56 seats; took majority (~228 of 391 Democrats vs. ~163 Republicans in the 62nd Congress) - **Senate:** Republicans held majority but Progressive Republican bloc grew - **Chambers flipped:** House — flipped from Republican to Democratic control - **Net change:** Major Democratic gains; intra-Republican Progressive-vs-Conservative split widening ## Notable - The **Payne-Aldrich Tariff** of August 1909 — Taft's signed tariff legislation raised duties rather than lowering them as the 1908 Republican platform had promised; politically catastrophic for Taft - The **Cannon Revolt** of March 1910 — bipartisan procedural revolution that stripped Speaker Joseph Cannon of his control of the Rules Committee, the operational beginning of the modern Speaker-as-procedural-manager role rather than autocratic-procedural-controller - The 1910 result substantially set up [[1912 Presidential Election]] — [[Theodore Roosevelt]]'s primary challenge to Taft was made operationally possible by the Republican congressional defeats this election produced - Democratic House majority enabled investigations of executive-branch corruption and progressive legislation that the prior Republican Congresses had blocked ## Connections - [[William Howard Taft]] — Sitting president; defeated for renomination 1912 in part on this election's signal. - [[Theodore Roosevelt]] — Out-of-office former president; the 1910 result encouraged his 1912 primary challenge.
