According to the National Conference of State Legislatures, Iowa is only one of four states with a legislature divided between Democrats and Republicans in the aftermath of the 2012 election. That was surprising to me.
The national picture:
In 20 of the past 28 presidential-cycle elections, the party winning the White House has gained seats in state legislatures. Thanks in large part to a Democratic gain of more than 100 seats in the New Hampshire House, it will be 21 of 29 winning years for the presidential party.
In the first state legislative election since redistricting, voters cast ballots in 44 states for men and women running for 6,034 state legislative seats. Democrats appear to have regained control of seven chambers that they had lost in 2010, but Republicans claimed four chambers previously controlled by the Democrats.
The biggest surprise of the election night was the New Hampshire House where Democrats won a majority. The preliminary numbers for the Granite State House are 217-177 (six undecided). Going into the election Republicans had a 288-102 margin, so the Democrats appear to have picked up at least 115 seats.
Arkansas was probably the biggest prize for the GOP at the state level. Republicans switched the Senate, and the House has a tentative 51-49 Republican majority, including one seat with a 44-vote margin that is subject to a recount. If the House numbers hold, this will be the first time since Reconstruction that Republicans have controlled the Razorback State.
