Indiana Representative Baron Hill, who introduced Senator Hillary Clinton at a rally just last Friday, today endorsed Barack Obama, becoming the fourth new superdelegate to throw support behind the Obama campaign in the last 24 hours.

“If we are going to develop real solutions for Hoosier (Indiana) families, for America’s families, we have to move past the partisan gridlock,” Hill said in a statement released by the Obama campaign.

“I believe both Senator Clinton and Senator Obama want to do that and I believe both are formidable candidates. But, I also believe that only one of them truly can.”

Hill joins Representative Andre Carson of Indianapolis in endorsing Obama ahead of the Indiana primary, which Obama himself has declared a ‘must-win’.

With the Hill endorsement, the Obama campaign now has the backing of four Indiana superdelegates, while Hillary Clinton claims the support of five, including the well-respected Senator Evan Bayh.

Three of the state’s other Democratic Congressmen have not backed either candidate.

The announcement comes at an important juncture as polls have shown a tight race between Clinton and Obama in Indiana as they seek the 72 pledged delegates at stake in Tuesday’s primary.
