(4) Looking at State legislatures (critical for redistricting), the Democratic Party says they have majorities in 70 of the nation’s 98 partisan chambers, up from 57 (MT and TX still undecided). Here and here are an interactive graphics.
At press time, only seven states have split legislative control: AL, IN, KY, OH, MI, PA, and VA. Democrats control 27 state legislatures, and Republicans have 14. At the time of this release, MT is undecided because control in the House remains up in the air. NB’s Legislature is nonpartisan and unicameral. Factoring in the results of the 11 governor races held this year, Democrats control all of state government in 17 states, Republicans have eight and 24 states have divided government. (source).
