Lawrence O'Donnell, already infamous for his in-your-face rant at John O'Neill of the Swiftboat Veterans, is at it again. This time, the object of O'Donnell's obloquy is Mitt Romney, and in particular his Mormon religion. Appearing on last night's McLaughlin group, O'Donnell indulged in an angry, protracted condemnation of Mormonism.

Excerpts:

• This was the worst political speech of my lifetime. Because this man stood there and said to you "this is the faith of my fathers." And you, and none of these commentators who liked this speech realized that the faith of his fathers is a racist faith. As of 1978 it was an officially racist faith, and for political convenience in 1978 it switched. And it said "OK, black people can be in this church." He believes, if he believes the faith of his fathers, that black people are black because in heaven they turned away from God, in this demented, Scientology-like notion of what was going on in heaven before the creation of the earth.
