Will.i.am insists he won't quit the U.S. if Presidential hopeful Barack Obama isn't successful in his bid for the White House - because he'd feel too guilty about leaving the country.

The singer is backing Obama to take the presidency over rival John McCain - but won't be too downbeat if the Democrat doesn't win the race.

He tells E! Online, "Whether Obama's president or McCain's president, it's still important for people to be just as passionate and just as involved in moving and shaping their communities.

"I'm going to do that regardless of who is president. You don't just bail the f**k out. This political cycle isn't like Christmas. On November 4, it isn't like I got my presents, and now I'm not gonna pay attention anymore."

The star has publicly backed the politician throughout his campaign, recording a pro-Obama music video with stars including John Legend, Ryan Phillippe and Jessica Alba.

Although will.i.am insists he isn't eager to make another political promo: "Not anytime soon. If I start making songs just like a factory, then they're not the truth.

"You have to be inspired to do that kind of stuff, and when an inspiration calls, I'll answer it and do it again."
