The New York Times posted a preposterous headline over Paul Krugman's latest column: "Bernie Sanders Isn't a Socialist." But he describes himself as a socialist. Our own Dan Gainor underlined the humor of this sentence with this joke on Twitter:  "Paul Krugman isn't a columnist."  Krugman admits Bernie identifies as a socialist, but he claims socialists really mean they're social democrats, so don't smear them with the S-word.
