So far word about who John McCain has selected to be his running mate has not leaked out, but who it isn’t has. Tim Pawlenty says he’s not headed to Dayton, Ohio, today for McCain’s announcement: “I’m not going to be there. I plan to be at the state fair. You can draw your conclusion from that,” Pawlenty said on his radio show.

And Mitt Romney is not going to Dayton, either.

As for who it might be, Alaska Gov. Sarah Palin’s name has risen again in the speculation. Marc Ambinder at The Atlantic.com tracks a plane from Alaska to Ohio.

Today, by the way, is McCain’s 72nd birthday.
