TOLEDO, Ohio (CNN) - Hillary Clinton has hinted that her campaign is willing to take the nomination fight all the way to the convention. But on Sunday, she refused to look past March 4.
"I intend to do as well as I can on Tuesday, and we'll see what happens after that," Clinton told reporters on her campaign plane late in the evening.
The New York senator, nursing a beer from of a red plastic cup, and accompanied by actors and longtime friends Ted Danson and Mary Steenburgen, was in a cheery and reflective mood before the plane flew from Cleveland to Toledo.
"I just have to get up every day and do the best I can to win as many delegates as possible," Clinton told one reporter. "But I feel good about where we are."
Clinton wouldn't answer to comments made Sunday by prominent Democrats like Bill Richardson and John Kerry, an Obama supporter, both of whom suggested Clinton should consider leaving the race after Tuesday if she fails to close the delegate gap with Obama.
She said only, "I've had a wonderful time campaigning and feel really good about where we are and I am looking forward to the results on March 4."
Asked if she has succeeded in illuminating differences between herself and Obama, particularly in recent days on the topic of national security, Clinton argued she is raising important issues.
"I think we have been sharpening the contrasts," she said. "And I think it's a contrast that needed to be sharpened, because this is a big decision for people."
