"Republicans have been busy in recent weeks seeking to achieve that: Texas, Indiana, Missouri and Florida have all either redrawn their congressional districts or floated the idea, in hopes of adding new Republican seats to the House. At Trump’s behest, the Texas GOP added five seats favorable to Republicans. Texas, Indiana, Missouri and Florida all have Republican trifectas — where the GOP controls both chambers of the legislature and the governor’s seat — making it much easier to consider redistricting.

But of the 15 states with Democratic trifectas, only Maryland and Illinois’ legislatures have clear pathways to redraw lines that could make seats more competitive for Democrats. California and New York, meanwhile, can ask voters to change state gerrymandering laws to redistrict down the road.  While new maps in Texas and California (if approved by voters) could cancel each other out by both adding up to five seats for each party in the House, the GOP’s additional targets of Indiana and Missouri could push Republicans a handful of seats beyond what Democratic states appear capable of flipping."
