And... AND - conservatives (the GOP) cannot make the mistake of compromise. For one thing, if/when the shit hits the fan, they cannot be part of that problem. Second, someone has to represent a platform that will be in position to fix the mess, and a mess there will be.
Having said that, I think the GOP is more concerned with party survival in the short run and will put themselves in a position of compromise.
Which is why I changed parties recently.
