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 non-partisan.) The following is a partisan breakdown of state legislatures prior to the November 2 election:

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.
