John McCain is determined to steal some of the attention away from Barack Obama when the Democratic nominee speaks tonight at Invesco Stadium. The camp is planning on releasing an ad later today that shows McCain speaking directly to the camera as if to Obama. Communications director Jill Hazelbaker referred to the spot as "historic" when she appeared on a morning talk show today.

The ad will air in battleground states around the time Obama will be accepting his party's nomination in Denver, Hazelbaker said on "Morning Joe." The campaign hopes that it generates buzz. "I'm not going to give away many more details... but suffice to say it's going to be a very exciting ad, and I think it's going to get a lot of attention."

Check back here later today for more on this ad.
