I don't see any potential for even that saving the US. There has to be a third party before anything positive can happen, and it will have to be a USA-first anti globalist party. Such a party will not emerge until the US has some kind of economic and/or social breakdown.
It will be interesting to see if any real anger is ewhibited by those who are supposed to be the real constitutional conservatives in the HOR and US Senate. They have to break all ties with the leadership or they're part of the problem.
No time to build an effective one. Need to change the one we have. The foundation is there to do it.
