A little more than 24 hours after Mitt Romney said he wasn't concerned about poor people, he accepted Donald Trump's endorsement in Las Vegas this afternoon. The two men standing onstage together made a hell of a picture. Romney could well be worth more than Trump, but the two men combined are probably worth somewhere around half a billion dollars.

Romney did not at all look comfortable—he seemed mildly aggravated, and eager to leave, all during the announcement. Ann Romney was flitting back and forth in front of the camera, urging her husband to say hi to prominent campaign donors. Her tense movements indicated that she wasn't aware a camera was running, recording her strange behavior. Though the Romney campaign set the event up, the candidate barely spoke three sentences after Trump's speech, drawing the whole thing to an abrupt close.

There are many reasons why the Romneys looked uncomfortable. There's the money issue, of course. And Trump has openly trashed Romney in the recent past, explaining that voters would turn away from Romney because of his Bain experience: "He'd buy companies. He'd close companies. He'd get rid of jobs." But most likely, Romney's discomfort came from the fact that everyone knows Trump is a bigoted birther who appeals to the dumbest, most hateful fringes of the Republican Party. In an ideal world, he'd have avoided personally attending this endorsement, but the support of the dumb, teabaggy fringes of the Republican Party is still very much in doubt. It'll be impossible for Romney to win in November without overwhelming support from the birthers and the racists and the xenophobes who like the way Trump talks because he dumbs things down to the point of irrationality. The truth is, Mitt Romney isn't strong or confident enough to say no to scum like Donald Trump. Mitt Romney isn't strong enough to say no to anyone. And the worst part, the most uncomfortable part is, he knows it.
