Highly dependent on specific state and town, mostly falls along the lines of rural/urban divide. For example in Chicago area where we spent a lot of years the further away you move from Chicago the more Trumpy it becomes. 30 miles out from Chicago it's about even mix between Trump and BLM/Rainbow signs depending on the neighborhood. Still lots of Trump/Punisher/Thin Blue Line decals on trucks, in restaurants and gyms. On one of my walks there used to be a fully decked out Trump house with 5-10 Trump/GOP signs. Sadly I can't find a good photo of the house right now, but it was every bit as bad as you can imagine, and to top it off the owner was clearly not taking good care of the property, I'd say it was about 5-10 years away from being condemned at the rate it was going. 40-50 miles out from Chicago it's practically Trump country, multiple 6 foot Trump flags, nothing else, a few years back somebody vandalized sledding hill in Fox River Grove with giant 20 foot letter sized spray painted Trump sign. After January 6th I've seen some people put away Trump signs, but I'd say it was a fairly small minority, and some put them back up after a while, honestly, at least judging by the yard signs I'd say Trump is basically just as popular as ever.
We've moved states about a year ago though, where we are now the yard signs are smaller and a lot less annoying, and they're mostly rainbow/love signs, but again, that's highly dependent on the area you live in.
