MOS Def has his own theory about America's love affair with presidential hopeful Barack Obama.

"America's too vain, and he appeals to America's sense of vanity," the rapper said in an interview with Rolling Stone's Anthony DeCurtis at the 92nd Street Y the other day. "It's the A & R guy in me . . . when I saw him on the cover of Men's Vogue, I said, 'This guy's gonna win because he looks good.' So, the best-looking guy for the job is a black guy. I'm cool with that. People also want a rock-star quality to the president, which he has."
