American leftists aren't that stupid. This already happened, Nixon did it in '72 causing Chicago to literally bulldoze them over. There is video of this still on Youtube. The modern left, or at least those who control the Democrats, grew up in the fallout of a 2nd Nixon term and won't let Trump completely destroy the Constitution.
If people riot over Gaza, which is the only thing with enough animation for violent protests at the DNC, Democrats will make an example of them for moderate votes and win Congress on that basis.
