While 201 House and Senate seats were in play in Minnesota, a net gain of 11 seats gave the Democratic-Farmer-Labor Party control of both houses in Minnesota. Gov. Mark Dayton also is a Democrat.
State DFL Chairman Ken Martin told the Minneapolis Star Tribune Election Night there was "an amazing turnout around the country and around the state for President Obama and the reality is that that's going to translate into votes for our legislative candidates."
The National Conference of State Legislature said the 2012 election saw a drop in the number of states with divided government, in which a governor of one party and at least one chamber of the Legislature are of opposite party.
After the election the number of states with a unified Democratic government was 14, unified Republican, 23, and divided, 12.
In the first state legislative election since the 2010 redistricting, voters cast ballots in 44 states for a collective 6,034 state legislative seats, NCSL said. Democrats regained control of seven chambers they had lost in 2010, but Republicans claimed four chambers previously controlled by the Democrats.
NCSL said the surprise of Election Night was the New Hampshire House where Democrats won a majority. Heading into the election Republicans had a 288-102 margin.
Thanks to a victory in Arkansas, Republicans gained control of the old South, turning the once solidly Democratic 11 states into red territory.

Soon after the results came in, the Republican Governors Association said the 30 GOP governorships nationwide is the highest number of state chief executives held by either party in 12 years.
"There's no doubt that the Republican Party's strength comes from the states, and the RGA's ability to expand our majority provides optimism for the future," said RGA Chairman Bob McDonnell, governor of Virginia, in a statement Nov. 6. "In the states, Republican governors are providing the type of results-oriented leadership. ... They've eliminated massive budget deficits while reducing the tax burden, reformed entitlements and long-term fiscal liabilities and enacted the most comprehensive education reforms in a generation."
The Democratic Governors Association, meanwhile, praised the effort to hold on to five of six competitive races.
"How did Democrats manage this?" Chairman Martin O'Malley, Maryland governor, wrote recently. "They focused above all on the top issues for voters: creating jobs and expanding opportunity."
