It's morning, and we still don't know who John McCain's running mate will be! Thus far, the name has not leaked out to the press. The McCain Campaign told Fox News that he will wait until 12 Noon EDT to announce his choice at a rally in Dayton, Ohio:

John McCain will wait until noon ET Friday to name his vice presidential running mate, senior campaign officials told FOX News.

They said no authorized leaks will go out overnight in deference to Barack Obama’s acceptance of the Democratic presidential nomination Thursday night.

FOX News confirmed Thursday that McCain had made his selection. McCain was scheduled to appear with his choice at a noon rally in Dayton, Ohio on Friday.

Massachusetts Gov. Mitt Romney, a short-lister on the vice presidential selection sweeps, is expected to be in Dayton on Friday. Former Arkansas Gov. Mike Huckabee, who like Romney was a former primary season rival to McCain, sent an e-mail to supporters on Thursday evening saying he will not be at the rally.

On Thursday afternoon, Gov. Tim Pawlenty returned from Denver to his home state of Minnesota, where the Republican National Convention will be held next week, and attended his daughter’s volleyball game during the evening. He said he planned to deliver his usual radio address at the state fair on Friday morning.

The McCain Campaign has done an impressive job of keeping this under wraps. Pawlenty insisted late last night that he has no plans to fly to Dayton, Ohio, which would seem to indicate he will not be the pick.

Pawlenty says he still plans to be at the Minnesota State Fair Friday, where he's to do his weekly radio show, and that he has no plans to fly to Ohio, where McCain is expected to announce his choice at a rally in Dayton Friday.

But most speculation still centers on Pawlenty and Mitt Romney. We should know very soon - in less than five hours at the latest!
