Bad leadership. Blue cities have fascist police, do not police them, are dirty and vulnerable to those cops if they do check them. But more than anything they are chosen to be weak, to not challenge entrenched interests.

Same with biden, hillary, kamala, et al. They win as rejection of the other party on the sheep that trust the ivy league suits on tv to lead them. Maybe 10 pc of the population. But they vote in primaries and are led by those ivy leaguers that prevent any real leaders challenging them.

People like mamdami, in every district. Including some white dudes, why are there no white left leaders contesting? They are suppressed by the controlled opposition and republicans and both of their donor bases. Killed in the cradle.
