Donald Trump won the overall popular vote by 1.5% nationally, and by roughly 200,000 votes spread over three states (PA, MI, WI).... small, subtle changes in the electorate over the next couple of years can and will make a huge difference.
It's not about the Trumpers, it's not about the "red hats" as you like to call them.... most of those people are just gone. But there's a slice of the electorate that doesn't follow politics as closely as your or I do, who maybe don't love Donald Trump but remember the economy as being reasonably good between 2017-2019 (memory holing how he ****ed up 2020). We pretend like these people don't exist, but they do....
The "leopards" and "FAFO" stuff is fast food for liberals, and it isn't without a modicum of truth, but in order to build a coalition to push back on these guys, there's going to have to be an acceptance of people who realize or admit that they were lied to by this administration. It's annoying, I'll be the first to admit it, but it's reality.
