If by "Endorses" you mean "Piles onto the eventual demise of"...

Then sure, what Dick Cheney did to John McCain was an endorsement. I mean, after all, endorse means "to approve, support, or sustain: to endorse a political candidate." yeah, that's what Dick Cheney did.

If we recall correctly, Congress' approval rating is below child molesters, right above Osama Bin Laden's, and that puts Dick Cheney's approval rating... right smack dab in the middle of "Please God, please oh please don't let him endorse me".

Maybe this was just Dick Cheney's backhanded way of endorsing Obama? Everyone else ever ever did anyway, so jump on board too, Dick.

McCain might as well say, "I need an endorsement from Dick Cheney like I need a shotgun shell to the face". Just sayin'.
