Silver's take on yesterday's results and the tea party movement:

There's not really any evidence that the...movement is yet anything more than an isolated and regional one. It will almost certainly have some implications in the South -- and if I were a Democratic Congressman there, I'd be very nervous. But only 18 of the 52 Blue Dogs in fact come from the South, and if I were a conservative Democrat in California, or South Dakota, or Michigan, I'd be feeling rather relieved.

The spin from the White House is similar.
