Romney and Pawlenty are out. According to Fox News:

Sources told FOX News that former Massachusetts Gov. Mitt Romney will not be McCain’s choice, even though Romney is scheduled to appear at the Dayton rally.

And Minnesota Gov. Tim Pawlenty told a Minneapolis radio station that he was not going to be in Dayton for the McCain announcement.

“I’m going to be at the [Minnesota] state fair,” Pawlenty said on WCCO. “I will not be in Dayton, Ohio, so I think that’s a fair assumption,” when asked if this was an indication that he would not be McCain’s running mate.
