I'm more pessimistic than that. I think systemic change or revolution in the US will inevitably be violent. The ruling class will not allow anything less, and I'm also afraid the good guys will lose that one.

I think the political system is already too firmly under the control of the Right wing oligarchs. The system can no longer be changed using the system. The system is too rigged.

Violence is out too as a solution. An army of Left wing protesters armed with assault weapons would be quickly out numbered by the NRA supporting Right wing militias, not to mention a regular army under the control of the president armed with tanks and helecopters, etc.

The only alternative I can think of is to establish an alternative political system and an alternative economic system.
