Karl Marx rolls over in his grave

Socialists and political scientists are objecting to John McCain's characterization of Barack Obama as some sort of Marxist:

"Obama is about as far from being a socialist as Joe The Plumber is from being a rocket scientist," said Darrell West, director of governance studies at the Brookings Institution. "I think it's hard for McCain to call Obama a socialist when George Bush is nationalizing banks."

But since when did McCain let anything like facts or book-learnin' get in the way of a good lie?
