Grant it to the liberals when they are funny:

Is Barack Obama a socialist? Well, let's see. His campaign platform makes no mention of proletarian revolution or nationalization of industry, and he trumpets his belief that "America's free market has been the engine of America's great progress. It's created a prosperity that is the envy of the world." Not quite Leninesque. On the other hand, Tom DeLay has made a logically rigorous counter-argument sure to convince second-graders everywhere: "I have said publicly, and I will again, that unless he proves me wrong, he is a Marxist." No word on whether DeLay proceeded to put his fingers in his ears and hum loudly.
