The McCain campaign isn't confirming the report, which grew out of a post Hamilton County Republican Party chair Alex M. Triantafilou's blog saying this: "Sen. McCain is expected to host a rally on August 29 in Dayton and is looking for a BIG venue and for a BIG crowd. He'll get it. This is not yet public. I guess I just made it so."
Politicker and The Cleveland Plain Dealer spoke to sources who (anonymously) confirm the planned rally. And as the latter suggests, political watchers are looking at the event as the scene of a possible unveiling of McCain's vice presidential choice:
McCain is expected at a noontime rally in Dayton on Aug. 29, right after the Democratic convention ends. That's a Friday, preceding the weekend when Republicans will converge on St. Paul, Minn., for the GOP convention. It also is a date that -- if you're prone to speculating -- could be ideal for announcing a McCain running mate.
