No more Mr. Nice Guy! First Matt Damontrashed the screenwriter of the 'Bourne' series, now he's bashing the president. Back in '08, Damon was one of Barack Obama's most passionate celebrity supporters, but today the actor is saying he'd have preferred "a one-term president with some balls." Ouch. "I've talked to a lot of people who worked for Obama at the grassroots level. One of them said to me, 'Never again. I will never be fooled again by a politician,'" Damon told Elle.
