Well, I'm not American so I'm maybe forgetting something, but for me, it's pretty clear that Democratic Party has no influence from Marxism. Even IIRC, some of the most anti-communist people during the Cold War were Democracts (Larry McDonald, Scoop Jackson).
As a Cuban-American whose parents knew real communism, I'm gonna go ahead and call bullshit on Democrats being Marx-influenced.
I'll take the bait on this one. My great-grandfather was murdered by communists.
Sorry about your great-grandfather, but you still have no idea what you're talking about. Fairness is not a Marxist idea, not even if you're claiming that you mean "redistribution" by it.
And calling Obama a Marxist is incredibly ignorant, as he has done nothing that Marxists actually do. He's not even very leftist.
