Wisconsin as a whole does tend to lean blue. The margins aren’t large though. Last mid term Evers (D) won for governor but the same election Johnson ® won for senate. The Democrat opposition for that election was Barnes, who was definitely progressive leaning, but ran a terrible campaign that the DNC didn’t help until it was too late. We are still a swing state.
isn’t the result of conservatives turning on Trump
Nobody is saying it is. It’s that group of swing voters that have immediately changed from liking Trump to rejecting Elon and Trump. You’ll never turn his cult base, but you also don’t have to.
You’re still underplaying what happened.
