A new radio ad in South Carolina from Sen. Hillary Clinton.... Magic Johnson implies that Barack Obama is a "hyped" "rookie" who needs more seasoning. Check it out:

This is Magic Johnson. On the court and in life, successful leadership comes from hard work and experience. That’s why I’m endorsing Hillary Clinton for President. We have great candidates this year, but I believe only Hillary is a proven leader, with 35 years’ experience dealing with challenges facing America. Are you looking for better jobs, universal health care, better treatment for veterans, opportunities for your children? Then you want Hillary Clinton for President. My rookie year, we won our first game on a last second shot. I was so hyped. But the captain of my team said, “take it easy rookie, it’s a long season, it’s a long road to the championship.” He was right. Winning comes from years of hard work and preparation. Whether it’s winning championships or a President who can lead us back to greatness, I’ll always want the most prepared and experienced person leading my team. That’s why I’m asking you to join me in voting for Hillary Clinton for President.
