You, my friend, are pissing into the wind. There are none.
Actually, there are. Just not very many. Jim DeMint is one, IMO. Now there's a guy who voluntarily gave up his "cushy elected position" to join an organization that he believes may truly be capable of advancing conservatism in America. As a senator, he royally pissed off the "leadership" (ie., the establishment GOP) by starting a PAC specifically for promoting tea party candidates.
I am hoping he runs for president.
