From the National Conference of State Legislatures:

Republicans made huge gains in state legislative races and are at their highest point since 1928.

The Alabama House and Senate, Indiana House, Iowa House, Maine House and Senate, Michigan House, Minnesota House and Senate, Montana House, New Hampshire House and Senate, North Carolina House and Senate, Ohio House–a big redistricting win–the Pennsylvania House, and the Wisconsin Assembly and Senate all have flipped from Democrat to Republican.

This is the first time in Alabama that Republicans have controlled the legislature since reconstruction. The North Carolina Senate has not been Republican since 1870. And Republicans have reportedly taken over 100 seats in the New Hampshire House. For the first time in history, the Minnesota Senate will be controlled by the GOP.

Make sure you check out the map NCSL has posted. It looks as red as the House and Governors maps now do.
