The Katrina stuff isn’t that odd; it’s followed by scenes of housebuilding to show, I guess, the indomitable American spirit. The Nixon farewell is a bit strange, but hey: liberals buy cars, too, guys. For some of us, a slice of cheesecake or beefcake leaning enticingly against the hood might be enough to pique our interest in the product. For others, archival footage of a Republican leaving the White House in disgrace might do the trick.
If Chevy were smart, they’d partner up with that Bush assassination film and really move some merchandise.
Update: Re: that language about Colbert, I’m 99.9% sure that was added by Jalopnik, the blog the ad on YouTube. That’s, uh, not part of the original commercial. I think.
