I say, let it roll! If the people in these cities are dumb enough to elect the Soros guy, then they will get the city they deserve. Let everyone see what happens when liberalism wins. Working people will leave these cities in droves.
The problem with your theory is the people who elect the Soros stooge usually don’t figure out what they did wrong. Instead, they leave the city for the suburbs, and continue voting for the same politicians who ruined the city to begin with. Democrat voters are like locusts.
