Los Angeles, May 5 (IANS) Actor-filmmaker Kevin Costner is not happy with the "political landscape" in the US.

"This is the greatest experiment in humankind: America. This great idea about America still exists, it's still here. People still want to come here, but we're not first in hardly anything that matters and we have an inflated idea about how we are.

"We exaggerate about what we are. We are everything that's great and we are everything that's human. And our humanness and our level of selfishness is overtaking our chance to be great," he said.

Costner campaigned for Barack Obama in 2008. Asked about the idea of Michelle Obama running for president, Costner said: "Michelle's incredibly bright and articulate and has possessed good judgement and experience as a result. Why couldn't she be (president)?"
