As for Marxists, yeah, that's the democrat crowd but don't forget the Trotskyites as embodied in Bill Kristol and others in the perpetual war, unipolar world, school of American 'conservatism'. There's no real difference between what they preach and what Trotsky preached once you strip away the buzzwords and flowers embellishing it to keep useful idiots in their camp.
They sponsor just as many trolls as the DNC and have a greater interest in places like FR than the Marxist crowd does.
Obamaite Marxists have taken over government, not Trotskyites. Bill Kristol is a mere talking head in the media and weilds little power. Marxists have assumed control over just about every agency in the United States government. It's as plain as the nose on your face.
