Mitt Romney's Trump-Sized Problem.

Hmmm, funny how that whole "guilt by association" thing works.

President Barack Obama's campaign is highlighting what they call Mitt Romney's "refusal" to condemn Donald Trump's continued highlighting of the "birther" conspiracy.

The release of a new video by the president's re-election team Tuesday morning comes a few hours after Romney appeared to downplay Trump's comments, and a few hours before Romney teams up with Trump at the business magnate and reality TV star's hotel in Las Vegas for a fundraiser for the presumptive Republican presidential nominee.

Asked on his charter plane Monday night whether Trump's questioning of Obama's birthplace gave him pause, Romney said he was grateful for all his supporters.

"You know, I don't agree with all the people who support me and my guess is they don't all agree with everything I believe in," Romney said. "But I need to get 50.1% or more and I'm appreciative to have the help of a lot of good people."

Wow, what a cowardly response. But what else would I expect from Mittens. Wasn't this guy calling for Obama to refudiate repudiate Fidel Castro's niece when she "endorsed" Obama last week? Never mind the fact that Mariela Castro isn't even an American citizen and was mostly endorsing Obama's stance on gay marriage. In Mittens Logic, this all makes perfect sense.

I'm not begrudging Romney's right to accept money from a poorly coiffed reality show host, but would it have really killed him to say that he unequivocally doesn't agree with Trump's birther claims? This sort of mush-mouthed "I don't really care" nonsense isn't really becoming of a Presidential candidate.

Then again, he needs to money. So there.

Question: Should Romney disown Trump's endorsement?
