The Democratic Party has about as much influence from Marxism as the Republican Party has from Nazism.
Both are ridiculously childish claims.
I try to stay away from it, but democrats are playing with fire and I won't let people pretend they aren't. For instance, tell me how Obama's concept of "fairness" isn't influenced by Marx. Are say French Socialists influenced by Marx?
So Marx is the first man to introduce the concept of "fairness?" More importantly, anyone who believes in it is automatically a Marxist? Yeah, okay.
Your outlook on politics is extremely narrow.
