Tentatively, the vote counts are not all in and the litigation is not all resolved, what was surprising to me was how well Republicans did, especially considering Trump's loss. The down ballot races in general went well for Republicans, they gained seats in the House and likely did not lose their small margin in the Senate. No state legislatures flipped from Red to Blue. This was not "The Blue Wave" nor was it a wholesale repudiation of the Republican Party.
Also surprising, no matter who ends up winning, was the gains that Republicans made among minority voters. They still have a long way to go, but they got more minority votes this time around than they did in 2016.
