According to the Huffington Post, Rep. James Clyburn from South Carolina, a ranking Congressman and House Majority Whip, is endorsing Senator Barack Obama. For the entire campaign Clyburn, a well-regarded elected official and representative of the Congressional Black Caucus, had remained neutral between Clinton and Obama.
Now, with Obama's chance for victory all but certain, and with Clyburn's expressed concerns over Clinton's race-based campaign approach, Clyburn's moving toward Obama.
Congressman Clyburn is the House Majority Whip in the 110th Congress, and is the third-ranking Democrat in the House behind House Speaker Nancy Pelosi and Majority Leader Steny Hoyer. He can carry a number of Superdelegate votes with him.
