IDK, I think a better question would be "What is the Right willing to give up on?"
I agree with you on the insanity that has encompassed the Left in recent years, but what really concerns me is that the mainstream Right is just as bad as the fringe Left. The 6 week abortion bill is just the most recent evidence of that.
If the Right doesn't bring itself more towards the middle, the left will get pulled further away from center to the fringe groups, in exactly the same way that the Right got pulled so far right by their fringe groups. The left and right have both lost the confidence of the people, and unless they both give up their crusading, we are going to end up with a violent uprising.
