Who has the MOST firepower in the US? The Military and police. Whoever controls the vote controls the military and police. The left isn't stupid enough to stand out in the streets and fight people because that doesn't solve the problem.

And Yes, Elizabeth Warren IS most definitely " Left wing", that was why she kept being attacked for her plans by the right as a " communist takeover" BS. because she was taking the wealthy's accumulated wealth and redistributing it to the poor... You do not need to be calling for violence in the streets to be leftwing.
