One of the things that has bugged me the most has been the reporting of this, which is basically the inverse of Joe Biden's "very narrow" victory, in 2020 as a "landslide" because it confounded expectations. I looked at the final results, Trump won Wisconsin by ~20,000 votes, he won Michigan by ~50,000 votes and he won Pennsylvania by ~150,000 votes. If 10,001 people in WI who voted for Trump voted for Harris, 25,001 people in Michigan who voted for Trump voted for Harris and 75,001 people in PA who voted for Trump voted for Harris, Harris would be President-elect today.
That shows the narrowness of the victory and just how weak Trump's governing majority is. Bob Casey may lose, but it looks like Slotkin, Baldwin, Gallego and Rosen all hung on. If and when Trump does something totally outrageous, he will lose the support of the ~75,000 people who voted for Trump and Gallego in AZ, the ~4,500 people who voted for Trump and Baldwin in Wisconsin and the 9% of all Trump voters who think he's "too extreme."
Republicans who believe this is the way and hitch their careers to his presidency will end up like Rudy Giuliani in four years. Trump has a unique ability, he played somebody on TV that had the same name as him for over a decade. It makes people feel they know him. It allows Trump to get away with stuff that is fatal to other politicians careers.
If you're saying Ron Johnson, spending four years kissing up to Trump is a good way to lose re-election in four years when the ~20,000 Wisconsinites who don't like Trump but voted for him anyway are exasperated by his antics.
The vaunted "great realignment' produced incredibly narrow margins and there's a very good chance Democrats win in four years and finally put this god foresaken Trump era behind us.
