NEW YORK (AP) - After vowing not to participate in this year's presidential election, Bruce Springsteen is supporting Barack Obama again, saying he believes Obama is the best person to lead America.

Springsteen posted a message on his website Wednesday night endorsing President Obama's re-election, saying he'd been "getting asked a lot about where I stand." The rock star will make his debut on the 2012 campaign trail Thursday at events in Iowa with former President Bill Clinton.

He also backed Obama in 2008.

Springsteen says he's behind Obama, who is facing Republican rival Mitt Romney in November, because of the president's views on the rights of women and homosexuals, ending the war in Iraq and tracking down Osama bin Laden.
