The blue shift that recolored congressional maps Tuesday also affected state legislature elections.

Nebraska has a nonpartisan, one-chamber state legislature, and questions about control over several other state legislature chambers, including the Michigan state senate and the Montana state house, are still open, either because elections returns have been late to come in or some races are too close to call.

Democrats started Nov. 7 with majorities in the state senates in 23 states and majorities in the state houses or equivalent bodies in 22 states, according to preliminary election results compiled by the National Conference of State Legislatures, Denver.

Today, the Democrats appear to have firm control over 25 state senates.

Control of the state senates in Iowa, New Hampshire and Wisconsin passed to the Democrats Tuesday, from the Republicans.

The Republicans have been in the majority in Michigan and in Oklahoma. The Republicans now are in a tie in Michigan and still have a chance at achieving a tie in the state senate in Oklahoma.

At the house level, the Democrats appear to have majorities in 31 states. Control seems to have passed to the Democrats from the Republicans in Indiana, Iowa, Michigan, Minnesota, New Hampshire and Oregon.

The shift in New Hampshire was especially dramatic. There, Republicans had held 242 seats and Democrats only 150 seats, and 8 seats were vacant.

Now, the Democrats hold 234 seats and the Republicans have only 156 seats, according to the NCSL.

Clear determinations of the status of the state houses in Montana and Washington were not available at press time.
