In addition to the GOP gains in the U.S., Senate, House and governorships it was an historic night for the party in state legislatures.
Here is the summary by Tim Storey of the National Conference of State Legislatures:
The Republican wave that swept over the states left Democrats at their weakest point in state legislatures since the 1920s.
Everything went in the direction of the GOP as Republicans seized new majorities in the West Virginia House, Nevada Assembly and Senate, New Hampshire House, Minnesota House and New York Senate, The West Virginia Senate is now tied.
Control of several legislative chambers was still up in the air early Wednesday as counting continued in several tight races that will determine control of the Colorado Senate, New Mexico House and Maine Senate.
The lone bright spot for Democrats was holding majorities in the Iowa Senate and Kentucky House.
The overall number of divided state governments will increase with changes in governor in places such as Massachussets, Illinois, Pennsylvania and Maryland along with the legislatures in West Virginia, Minnesota and New York.
UPDATE: Republicans have taken control of the Colorado senate and the New Mexico house. They also have a chance to win the Colorado house and the Washington house, after mail-in ballots are finally counted. The state legislative chambers now stand at 65 Republican, 23 Democrat, 1 tie, and 4 undecided.
