ABC News' Rick Klein Reports: 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.As Willie Nelson's classic "On the Road Again" blared, Edwards leaned out of a window of his campaign bus dubbed "Fighting for One America", to hear an off-camera voice howl, "I wanted to ask ya, is it required that everyone go see "Fahrenheit 9/11" and "Sicko"?Edwards, in between autographs outside Dan's Pizzeria in Onawa, Iowa, replies, "I watched Sicko," later adding, "It's a great movie."You can watch the moment captured by C-SPAN and spread to the world on YouTube by clicking here.Is this a cinematic flip flop? Another hairy situation for the Edwards camp? As they say in the NFL, after further review, ABC News says it may not be so.With the help of our able colleagues at ABC News Radio, we isolated the audio, enhancing it to hear a key phrase that Edwards says between his claim of seeing "Sicko" and proclaiming it "a great movie."In the exchange, barely audible over the twang of Willie, Edwards adds, "I didn't quite get to see the end."While not a silver bullet, the exchange begs the question: does one really need to see the end of "Sicko" to know that communist Cuba provides government-run healthcare?
