Obama, Clinton add endorsements

John Edwards is one of the biggest Democratic fish that neither Hillary Clinton nor Barack Obama have reeled in, but some of Edwards's key backers in his home state announced today they are throwing their support to Obama ahead of the May 6 primary in North Carolina.

The Obama campaign said that 49 prominent supporters of Edwards -- including Ed Turlington, the former North Carolina senator's former national chairman -- have signed on.

"Barack Obama and John Edwards share a commitment to taking on special interests and standing up for regular Americans. Along with Edwards supporters from across the state, I am honored to join Senator Obama's movement for change,” Turlington said in a statement issued by the Obama camp. “As president, he will bring together Democrats, Republicans and Independents behind an agenda of change. From ending the war in Iraq to confronting the scourge of poverty to making health care affordable for every single American, Barack Obama will bring our country the change we need.”

Meanwhile, after her win in Pennsylvania, Clinton picked up a noteworthy superdelegate: US Representative John Tanner of Tennessee, a co-founder of the Blue Dog Coalition, a group of Southern conservative Democrats in Congress.

"I do not remember a time when our nation has faced the financial peril that confronts all Americans," Tanner said in a statement issued by the Clinton camp. "To me, this election is not about politics as usual. I believe nothing less than our financial liberty and economic freedom are at stake. In my opinion, the best person to lead this critical effort is Hillary Clinton. Hillary is a smart, pragmatic leader who understands the grave situation our country faces."
