But WHY do they want the cities they control, crime ridden?

Demonrats live in a lie filled world, men in dresses are women, demented old men are sharp as tacks, open borders protect you from crime and victims ask to be victims. Their biggest lie is the worst one of all, "they will protect the people" anyone dumb enough to fall for that one is doomed.

Liberals/Progressives/Leftists . . . they are all insane; although some of them probably vary in the intensity and breadth of their insanity.

The CLM will be doing the rioting this year

I wouldn't put it past them.
