The former first lady weathered a two-pronged blow Friday, with influential Pennsylvania Sen. Bob Casey Jr. endorsing Obama and another Senate colleague, Vermont Democrat Patrick Leahy, urging her to step aside. But to hear Clinton tell it, it was just another day in an epic primary battle whose result is still not known.
"I believe a spirited contest is good for the Democratic Party and will strengthen the eventual nominee," she said. "We will have a united party behind whomever that nominee is. ... I look forward to campaigning over the next several months."
Traveling across Indiana, the former first lady was greeted by large, enthusiastic audiences who roared their approval at her proposals to help fix the state's economic challenges.
At events here and in North Carolina on Thursday, Clinton raised the issue of whether she should quit the race, only to have it firmly batted down by her supporters.
"There are some people who are saying, you know, we really ought to end this primary, we just ought to shut it down," she said in Mishawaka, Ind., drawing cries of "No, no!" inside a packed gymnasium.
In Hammond, she compared the state's struggling steel industry to her own efforts to fight the odds.
"I know a little bit about comebacks," she said to cheers. "I know what it's like to be counted down and counted out. But I also know there is nothing that will keep us down if we are determined to keep on."
Yet despite the optimistic talk, there is no doubt that Clinton faces an uphill battle to secure securing her party's nod.
She trails Obama among pledged delegates and is not expected to close that gap even with a strong showing in the 10 remaining primaries. She also trails in the popular vote and probably cannot make up the deficit without revotes in Michigan and Florida, whose January primary results were nullified because they broke party rules. Neither state is expected to go through with new contests.
