Matt Damon feels let down by Barack Obama

Matt Damon has admitted that he is "disappointed" by Barack Obama's performance as U.S. President so far - insisting the public is feeling "let down".

"The Bourne Supremacy" actor pledged his allegiance to Obama's presidential campaign when he ran for the White House in 2008, and was ecstatic when the Democrat became the first mixed race president of the U.S. in January 2009.

But Damon feels Obama has not lived up to expectations, and is wary of the leader's controversial healthcare plan, which aims to give poor Americans free medical treatment.

Speaking with the New York Daily News, Damon said,

"Politics is compromise. I'm disappointed in the healthcare plan and in the troop build-up in Afghanistan.

"Everyone feels a little let down because, on some level, people expected all their problems to go away. But real change comes from everyday people. You can't wait for a leader."

Damon stars in "The Green Zone", a new political suspense thriller about a political plot around the days immediately following the invasion of Iraq.
