All these loopy teabaggers have been incredibly useful to them because they'll act up in ways which the Rethugs don't wish to (so Rethugs can further their "kind, Christian, upstanding" image they think they've carefully crafted). Of course, it's readily apparent they're just a glut of greedy tin god opportunists.
I'd also compare the Rethugs' approach to a villain who crafts two identities--one handy for the world, and an alter-ego for private crimes.
Except...the Tea Party alter-ego is a public phenomenon, so it has posed uncomfortable problems as it seeks to becomes more independent from Grand Ol' Evil Gepetto. Regardless, I predict that the Rethugs will always let the Teabaggers rampage like b~shirts without any kind of real repercussions, because it suits them just fine. Oh sure, there will be "distancing".
Rethugs will publicly distance themselves at times, but Teabaggers will remain a viable asset of the Rethug campaign to take back the White House.
And they can always say, with a secret glee: "Hey--that wasn't us."
