SOUTH BEND — Rep. Joe Donnelly says everyone from a former president to his own family has given him input on who to support in the race for the Democratic nomination, but he still has not decided.

Donnelly is a superdelegate, a group of party leaders and elected officials who are not pledged to any candidate. Analysts say they could decide the nomination.

Donnelly says he talked with both Sen. Hillary Clinton and Sen. Barack Obama in Washington, just days after the contentious Indiana primary campaign ended.

“The conversations were to tell them how much I appreciated the fact that they came to our state on a constant basis, that they looked us in the eye, that they talked to us about the issues,” Donnelly said.

Both have been trying to get superdelegates on their side to gain an edge.

"The sooner that superdelegates make their decision, the sooner we'll have a sense of who the nominee will be and the sooner we can focus on John McCain," Obama said in Washington, D.C. Thursday.

But Donnelly didn't commit to either of them.

“I told them I would wait a few weeks to kind of try and add everything up and make a determination trying to make sure we do what's right for our country," Donnelly said. "And the judgment I'm going to make is who would be the best president for our country."

Obama campaigned for Donnelly in 2006 and has given thousands to his campaign this year, but Donnelly doesn’t feel any obligation to support him.

“I do not," he said. "I've spoken with both President Clinton and Senator Clinton. And so, I thought that she worked very, very hard in the state as well. Senator Bayh is a very good friend of hers."

Donnelly says in the end, the superdelegates may not decide the nomination at all.

“I think what's going to happen is the superdelegates will simply be a small add-on, that the decision is going to be made by the voters, which is the way it should be.”

Democratic National Committee Chairman Howard Dean has said he wants the superdelegates to make a decision by early June. Donnelly says he should have a decision by then, if not before.
