John Edwards, Airhead

When an Iowa resident asked former senator John Edwards Thursday whether the United States should follow the Cuban healthcare model, the 2004 vice presidential contender deflected the question by saying he didn’t know enough to answer the question.

"I’m going to be honest with you — I don’t know a lot about Cuba’s healthcare system," Edwards, D-N.C., said at an event in Oskaloosa, Iowa. "Is it a government-run system?"

But just three days earlier, the candidate was asked a question about the Michael Moore documentary "Sicko" — which focuses extensively on the Cuban healthcare system.

Edwards, in between autographs outside Dan’s Pizzeria in Onawa, Iowa, replies, "I watched Sicko," later adding, "It’s a great movie."
