FWIW, a few weeks ago I went to a Midwestern county fair. The state went blue in 2020 but this particular county voted 60% Trump, higher than the one in the article (56%).
Before I arrived I braced for the worst.
Nothing. No one sold Trump merch. At most I saw one or two people who brought their Trump hats or t-shirts. There was a monster truck show and the announcer never mentioned politics. I counted a handful of Trump bumper stickers in the parking lot.
Zero Trump yard signs spotted on the road back to where we were staying, even though there were lots and lots of yard signs for various county or municipal candidates. So they weren't completely disengaged politically.
I'm sure many of the people I saw will vote for Trump again this year. But they weren't so willing to advertise that.
