The difference between the left and the right is that many Republican voters will vote for a candidate based on a single issue, while many Democrat voters will not vote for a candidate based on a single issue.

I’m genuinely not sure if there is a set of policies the left can offer which will adequately appeal to their entire base. I think the best case is another 2008 Obama who didn’t actually campaign on much hard policy other than just idealistic “hope”, which meant that a lot of voters could see what they wanted in him.

Meanwhile Republicans will continue to destroy the country while throwing out scraps like marginally lower taxes (but much lower for the rich).

Everyone loves to bag on boomers, but they’re actually more left leaning than they’re given credit for (more so now after Covid killed a lot of antivax seniors). Gen X is the MAGA stronghold.

Is there any past comment or behavior that would suggest Trump wouldn’t run for a third term, if given the chance?

Well he definitely said that in 2020, and if someone had had the foresight to ask him in 2016 he probably would have said it then as well, so I’m going to go ahead and be a little skeptical here.
