I would be quite surprised if he did such. Please provide a link. Bruce is quite Conservative. I can't imagine him voting for Obama.
I have to agree with his comments on Mitt. He knows clearly that Mitt is a Statist and will do absolutely nothing to turn our Republic around.
"Bruce himself speaks in a markedly modulated voice, one so low in volume and pitch that at times it's hard to hear him. It's almost as if he's controlling his tendency to speak his mind -- something that, in the past, has led him to misrepresent his own views. Take, for example, the fact that much of America believes Bruce Willis to be one of the most conservative actors in Hollywood, second perhaps only to Mel Gibson. Though he did support George W. Bush in 2000 and attended the Republican National Convention in 1992, Bruce has spent multiple interviews trying to explain away or modify previous political delcarations -- like the time he told reporters that the U.S. should invade Colombia to end drug trafficking.For the record, he says, he voted enthusiastically for Barack Obama in the last election, and his musings on politics the day we meet sound like those of a bona fide bleeding heart..."
Following that, there are quotes about his work promoting foster care and how he did that during George W. Bush's administration, and will continue to do the same during the current one.
