This pretty well sums it up:
Glenn Harlan Reynolds: Tea Party dominance was inevitable -- and I told you so | Washington Examiner: "For now, Republicans are (sort of) the beneficiaries. Though Tea Partiers aren’t happy with the GOP, they’re much less happy with the Democrats. In this election cycle, Republicans will benefit. But Tea Partiers are also taking over the GOP from the bottom up, running for precinct chairs and state committee seats.
This makes sense: There are barriers to entry for third parties, and it makes more sense to take over an existing party than to start from scratch, if that’s possible.
But those establishment GOP figures who think that they’ll cruise to victory and a return to the pocket-stuffing business-as-usual that marked the prior GOP majority need to think again. This election cycle is, in a very real sense, a last chance for the Republicans. If they blow it, we’re likely to see third-party challenges in 2012, not only at the Presidential level but in numerous Congressional races as well.
For the national GOP, it’s do-or-die time. So guys, you’d better perform -- unless you want me to be writing another “I told you so” column in 2013. And trust me, you don’t."
