Could this be a harbinger of things to come for McCain's chances with African-Americans this fall?

Politico:

A reader notices an odd choice, or oversight, in John McCain's latest television spot: The woman at left is wearing an Obama t-shirt. Now that's bipartisanship. Or something. Also perhaps an indication of how (unsurprisingly) hard it's going to be for McCain to build any African-American support at all.

UPDATE: Seeing some skepticism in the comments, I took the liberty of juxtaposing an enlarged screenshot (with adjusted contrast) with a close-up of the actual Obama shirt. I don't want to turn into a right-wing investigative blogger here (because it's really not a big deal either way), but it seems pretty obvious to me that, at the very least, you can't completely rule out the possibility that it's an Obama shirt. To me, the blue circle above the stripes is the tell-tale sign.
