Bennet, fresh off a primary victory over former state House Speaker Andrew Romanoff (D) Tuesday night, said it was too soon to say whether he wanted Obama to campaign with him.

"We'll have to see," the freshman senator said on "Good Morning America" when asked if he wanted Obama to come to Colorado to campaign.

"We'll obviously do what's right for the campaign. He's been a huge help and I appreciate his endorsement," Bennet said. "And we'll see what happens between now and November."

Obama endorsed Bennet in the primary, an election that was seen as somewhat of a proxy battle between the president and former President Clinton, who had endorsed Romanoff. Bennet has said Obama's backing helped, but wasn't conclusive in delivering victory.

The senator's victory delivered sighs of relief at the White House, which had also sought to battle an emerging storyline that the president was politically toxic to Democrats, who are fighting to retain their House and Senate majorities.

When pressed about his noncommittal answer on an Obama appearance, Bennet said it was too soon to tell.

"You know, I just won the primary about six minutes ago, so we're going to have to give it some thought," he said.
