Add another superdelegate for Obama

In an on camera interview with NBC's Andrea Mitchell, Rep. John Lewis -- one of the most influential African-American members in Congress -- has said he will support Obama as a superdelegate. Congressman Lewis had endorsed Clinton last year, but says that Obama's candidacy is a "movement and something in American politics that cannot be ignored."

Lewis has said his decision to change from Clinton to Obama was harder then his march across the bridge in Selma 43 years ago when he was beaten and bloodied by Alabama State Troopers. Lewis tells NBC's Andrea Mitchell he has put a call into Senator Clinton but has not yet informed her of his decision and has not yet told Senator Obama.

Adding one to Obama's superdelegate total, and subtracting one from Clinton, the superdelegate count is now Clinton 255 and Obama 201.
