I'm afraid RINOs are the party. Big spending, self agrandizing, power hungry, socialists are the Republican party. They have become the true Republicans, and one of their kind will carry the Republican banner in the next presidential election. It has become silly to call liberal Republicans RINO's when they are, in fact, the heart of the Republican party.
I can't help but see a new party rising out of the ruins of this debacle much the way the Whigs went away and the Republican party became ascendant with Lincoln. Something like that must be in the cards, because the sun has set on the Republican Party.
