It's true that there is no single Tea Party, but there are two branches that have been co-opted by cons, and the most prominent of those is the Koch Brothers Tea Party. The other is commandeered by Norquist, but they're as good as hand-in-glove as both present the most serious challenges to the Republican establishment in the primaries. They're basically gutting the Republican Party which has been left mortally wounded by Dubya's regime...which is why cons prefer that you develop amnesia about the Dubya legacy.
We won't let 'em forget, tho, you can bet on it.
