Republicans won't be able to make major gains from redistricting after this landslide.
Redistricting will, however, let them keep many of their otherwise vulnerable "less astute" newly elected members.
Agreed. A few of the Republican gerrymanders in 2000 were stretched too thin and got swept away with the wave. If they are smart this time they will simply try to consolidate their gains and give the Dems some safe districts packed with Dem voters instead of trying to wipe them out, which will make their own incumbents safer. This will give them a great structural advantage and make the seats less competitive, which would favor them.
