Impact on legislative majorities

See also: Partisan balance of state legislatures

Heading into the November 2 elections, the Democratic Party held a commanding lead in state houses in the 88 legislative chambers that held elections in 2010. 52 of the 88 chambers, or nearly 60% of them, had a Democratic majority, while only 33 of them had a Republican majority. (Two chambers had an exactly equal number of Democrats and Republicans and one is officially nonpartisan.) The following is a partisan breakdown of state legislatures prior to the November 2 election:

Legislative chamber Democratic Party Republican Party Purple.png Grey.png
State senates 23 18 1 1
State houses 29 15 1 -
Totals: 52 33 2 1

As a result of the election, Republicans picked up 20 legislative chambers while Democrats lost 20. Republicans won 53 total chambers on November 2, while Democrats won only 32. The following is a partisan breakdown of state legislatures after the November 2 election:

Partisan breakdown after the November 2010 Election
Legislative chamber Democratic Party Republican Party Purple.png Grey.png
State senates 16 25 1 1
State houses 16 28 1 0
Totals: 32 53 2 1

Another way to examine the data is to gauge how many chambers had gains for the Democratic Party versus the Republican Party. Using this variable, the wide-sweeping Republican victory is further amplified. Democrats bolstered their majorities in only 7 of 88 (7.96%) state chambers. These legislatures are as follows:

State legislative chambers where Democrats gained seats on November 2
State Chamber Number of seats gained by Democrats
California Assembly + 2
Delaware House + 2
Hawaii Senate + 1
Maryland Senate + 2
Massachusetts Senate + 1
Missouri Senate + 1
West Virginia Senate + 1

In 7 chambers, the GOP kept their current number of seats. In one chamber, the California State Assembly, both major parties gained seats by filling 2 vacancies and defeating an incumbent independent. Overall, the Republican Party picked up legislative seats in 75 (85.2%) of the 88 legislative chambers that held elections on November 2.

Impact on State Politics

Along with the GOP capture of the U.S. House of Representatives, state Republicans gained trifectas (control of the governorship, house, and senate) in 12 states. The following is a breakdown of trifectas across the nation, before and after the 2010 election:

Trifectas before and after the 2010 Election
Party Before election U.S. House seats After election U.S. House seats Gain/loss states Gain/loss congressional seats
Democratic
16 131 11 115 -5 -16
Republican
8 66 20 198 +12 +132

Before the election, 131 U.S House seats were in states with Democratic trifectas, while 66 districts were in states with Republican trifectas. After the election, Republicans trifectas control redistricting for 198 U.S. House seats while Democrats control only 115. Additionally, California, the strongest Democratic trifecta with 53 U.S. House representatives, passed propositions that take redistricting power away from state government.
