Macomb County is where the term “Reagan Democrat” was popularized by Democratic pollster Stan Greenberg... Macomb County, where Trump won in 2016 by a whopping 48,000 votes, helping him carry Michigan by less than 11,000 ballots.
This is merely anecdotal, I know, but I am seeing far, far more Trump signs here in my Michigan town than 4 years ago. Not just small Trump signs, but billboard sized signs. I live in a neighborhood on a lake and people have Trump signs on their pontoons. My next door neighbors have a giant purple and white Trump banner laying flat on their roof. You can see it from across the lake. His support here is palpable. Remember, our governor is very unpopular and she stupidly picked a fight with Trump.
