electoralism

don't really know what a yimby is.

YIMBYs are mainly polite-sounding ethnic cleansers. They're "woke" (imagine those quotes are larger for the correct effect) gentrifiers. People are right to be disgusted with them, though as you point out they have some support among the American public.

Like people are genuinely convinced that he's a fraud like a politician from a move when the actual analysis is that he's going to fail to implement his policies.

I mostly agree (he probably means well and thinks concessions are practical and will help him get things done), but sadly the difference in the outcome is not very large.
