George W Bush: Kanye Picked a Punk to Play Me

George W. Bush isn't upset about Kanye trying to find a look-alike to portray him in his new music video, but he's somewhat indignant the faux Bush lacks muscle.

In case there was any question, a rep for the 43rd Prez tells TMZ, "In case there was any doubt ... that is not President Bush."

The rep added it should be obvious the guy in the "Famous" video is a fake Bush, adding, "He [W] is in much better shape."

Picking W is an interesting choice ... you'll recall during Hurricane Katrina, Kanye ranted, "George Bush doesn't care about black people."

Earlier today Donald Trump's rep also told us what's pretty obvious ... it ain't him. We're guessing it's not Bill Cosby either.
