Mittens!

Ambinder:

So -- two senior McCain campaign officials confirm that John McCain will appear with his vice presidential pick in Dayton, Ohio tomorrow at noon ET.

And Gov. Mitt Romney expects to be in Dayton, Ohio tomorrow, having been asked there by the McCain campaign, a reliable source close to Romney says. (Another source says Romney will be in Boston.)

Gov. Tim Pawlenty is currently at the governors' mansion in Minneapolis. There is no guidance about his schedule.

We don't know if all the VP hopefuls have been summoned to Dayton; we don't know if some have. (MIke Huckabee won;'t be going.)

Maybe Romney knows how many houses McCain owns?
