The McCain folks go nuclear

If you want a sense of how the McCain camp is looking at this "house" thing, now they've got the outside groups trying to help them out. One group launches an ad trying to tie Obama to Bill Ayers, and another launches a website trying to tie Obama to Rezco.....

...and they both suddenly decide to spin up this afternoon.

(The campaign is also hurriedly firing out its own Rezco ad.)

The McCain camp is firing every bullet they've got right now. That should tell you how seriously they view this.
