Is will.i.am angling for a job in a Barack Obama White House? The Black Eyed Peas frontman on Friday released another star-studded music video in tribute to the presidential campaign of the Democratic senator from Illinois - this one is titled "We Are The Ones."Backed by a simple vocal refrain of "O-BA-MA! O-BA-MA!," stars such as Jessica Alba, Ryan Phillippe, Kerry Washington, George Lopez and others explain why they support Obama, while others such as Macy Gray croon the candidates' last name to the will.i.am-penned melody.The song is a follow-up to his inspirational video "Yes We Can," a viral sensation that has garnered more than 5 million hits on YouTube.com alone. That song features Obama's voice from a New Hampshire concession speech set to will.i.am's music and melody.The "We Are The Ones" video comes before Tuesday's Democratic primaries in Texas and Ohio. Obama is leading his rival, Democratic Sen. Hillary Rodham Clinton of New York, in the delegate count for the nomination.
