Presidential candidate Sen. Barack Obama has garnered a ton of support from celebrities and musicians, especially the hip-hop community, so it was a little jarring to hear that Puerto Rican rapper Daddy Yankee was backing Republican Sen. John McCain. The Reggaeton rapper appeared at a Phoenix high school to offer his official endorsement. "I believe in his ideals and his proposals to lead this nation," Yankee said. "He's been a fighter for the Hispanic community." Yankee's endorsement sparked fellow Puerto Rican MC Fat Joe's response.

"Put this in the MTV News headline: 'Fat Joe Says Daddy Yankee Is a Sellout,' " Joe told MTV via phone from Denver, where he's attending the Democratic National Convention. "Just like that! I gotta go in. I'm talking to little cousins that like [Yankee] and all that, and they're starting to believe that John McCain is [the best candidate]. I can't have that."

Joe went on to say that he's sickened by Yankee's actions and feels that it's a publicity stunt. "The reason why I called him a sellout is because I feel he did that for a [publicity] look, rather than the issues that are affecting his people that look up to him," Joe explained. "How could you want John McCain in office when George Bush and the Republicans already have half a million people losing their homes in foreclosure? We're fighting an unjust war. It's the Latinos and black kids up in the frontlines, fighting that war. ... We over here trying to take the troops out of Iraq and bring peace. This guy immediately wants war. If not with Iraq or Afghanistan, he'll start a new one with Iran. I feel real disgusted that Daddy Yankee would do that. Either he did that for a look, or he's just not educated on politics."
