Twenty-four states will be controlled by Republicans, including Alaska and Wisconsin, where the party took the State Senate, and North Carolina, where the governorship changed hands. At least 13 states will be Democratic, including Colorado, Minnesota and Oregon, where control of the legislatures shifted, and California, where the already dominant Democrats gained a supermajority in both chambers. (The situation in New York, where the potential for single-party control by the Democrats rests on the makeup of the Senate, is still uncertain.)…

Either way, the result is likely to speed along state legislative proposals from both corners, experts said, but less so from the middle.

“We are going to see government activism to the left and to the right that we haven’t seen in years,” said Lawrence Jacobs, a political scientist at the University of Minnesota. “If you wondered what Washington would look like under single-party rule, the states are a laboratory for that now.”
