Another consequence of the election: Prior to the election, Republicans controlled 15 State legislatures, Democrats 27. Eight were split.
Post election: Republicans control 26, Democrats 16. Four are split and four remain to be decided. This is a complete flip. Republicans took both houses in Alabama from the Democrats. The Republicans have not controlled both houses since Reconstruction.
What is the consequence? We just completed the Census. The legislatures and/or governors will control the redistricting process that will result. As long as they don't draw districts to dilute the vote of protected classes, it is legal for them to gerrymander in a way that favors their party. I hope the Republicans don't. I'd just like to see them eliminate much of the gerrymandering that currently exists and currently favors the Democrats.
Computers should be used to draw districts with humans polishing the districts so lines don't go through the middle of small towns. Even major cities should not be split unless the population warrants more than one representative. Here in Alabama, the Dems gerrymandered a district that included west-central Alabama, part of Montgomery, and then ran up I-65 to include part of Birmingham, when metro Birmingham could make up the bulk of one district, and metro Montgomery could make up the bulk of another. Ironically, that gerrymandered district is the only remaining Dem district in Alabama!
Anyway, whether the redistricting is done logically or by partisan gerrymandering, Republicans stand to pick up House seats next election due to a drop in primarily Dem districts and an increase in primarily GOP districts.
Elections have consequences.
