Something most don’t realize is that in the 2020 election, non-statewide races not affected by counting in large cities went decisively to Republicans, winning not only all tossup races, but also multiple races that were expected to be won by Democrats, and that was before Biden broke everything he touched.
There is definitely a problem affecting statewide races, and magic tricks generally don’t work twice (once exposed), but whether or not well-mannered Republicans are serious about fixing that problem remains to be seen, so we will see, but I would be uncomfortable if I were a Democrat.
