If Mitt gets the nomination, even if he wins the election, we need to start a new party on Nov. 7 which excludes the GOP establishment. At a minimum it should help scare Willard to right on his policies, should he win.
That would work very well with a Parliamentary system, but we don’t have one. If Mitt is the nominee, the only way to have influence is to threaten to withhold support but not rule him out entirely.
