The amazing Adam Weinstein writing for Gawker:

Rubio has two major political achievements. First, he was speaker of the Florida House of Representatives—an annual beauty pageant of ugly Republicans, by ugly Republicans, for ugly Republicans, so that ugly Republicans shall not perish from the earth. Second, he took an election from political changeling Charlie Crist, something that a reanimated pygmy skink could do, and has done. The thickest section of Rubio's resumé is his involvement in some truly ghastly internecine political and financial corruption. But he's running against a Clinton, a Bush, and a Texan. So much for that advantage.

Sure: On paper, Rubio looks like a formidable candidate, a nod to consensus wisdom on Republican electoral demographics. Part of the problem is not with him, so much as with the contradictions inherent in that wisdom. He sounds like a doctrinaire conservative, who hates social welfare and undocumented immigrants and alternate lifestyles. But! He's young and Latino! Who better to deliver a grumpy retrograde anti-minority vision of America's future?

Go read the whole amazing thing. Seriously. A couple of paragraphs can't do Weinstein's epic takedown justice. Read it. Oh, and when Rubio told Jake Tapper that he believed the states should be allowed to make their own choices about same-sex marriage and that he had never, ever supported a federal constitutional amendment banning same-sex marriage? He was lying.

UPDATE: Marco Rubio's church sounds like a good time.
