HENDERSON, Nev. - Reminding a crowd here that she and Senator Barack Obama "may have started on two separate paths but we are on one journey now," Senator Hillary Clinton urged her supporters in this battleground state to work for her former rival this fall.

"Anyone who voted for me or caucused for me has so much more in common with Senator Obama than Senator McCain," said Mrs. Clinton, referring to the presumptive Republican nominee. "I urge you who supported me to remember who you were fighting for in that campaign."

The New York senator, who ended her bid for the Democratic presidential nomination in June, is campaigning on behalf of Senator Obama in this state and in Florida later on this month. Her appearance here came on the heels of remarks she made hinting that her delegates may be entitled to a "catharsis" at the national party convention at the end of this month. And there were those in the audience today who still lamented the fact that she is not the presumptive nominee.

She spoke today in the same high school gym where her husband, former President Bill Clinton, bitterly complained about Obama campaign tactics a few days before the Jan. 19 Nevada caucuses. In another show of unity, she was introduced by Jeff Raithel, one of her most avid Nevada supporters, who told the crowd he was now throwing his support behind Senator Obama.

"I want to remind all of us that there are no guarantees, that it should be self-evident that we're going to win in November, but winning presidential races in the fall has been challenging for Democrats," Mrs. Clinton said, urging attendees to work for her former rival.

Yet while Senator Clinton and others insisted those wounds needed to heal for the good of her party and the nation, some of her die-hard fans who attended discounted her party-unity message.

"She was a puppet, she used somebody else's words," said an angry Florence Chesonis, a delegate for Senator Clinton at the Nevada State Democratic Convention. "I'm disappointed and I'm sad."

Ms. Chesonis and her neighbor Helen Gorman complained about the methods of determining who won the Nevada caucuses. Senator Clinton appeared to win most of the state on Election Day but later, because of a set of complex rules that gave greater weight to more sparsely populated parts of the state, Mr. Obama actually garnered more delegates.

"There's some kind of a machine working against Hillary Clinton," said Ms. Gorman, 78, a lifelong Democrat who said she switched her registration to independent after the caucuses.

Others, including Sonja McDonald, 37, of Las Vegas, said folks like Ms. Gorman and Ms. Chesonis "really need to get over it." Ms. McDonald, who was torn between the two during the primaries, now believes "we can't hang on to sore grievances. The bottom line is getting a Democrat into office."

Senator Clinton was more relaxed and light-hearted and less fierce than she was the last time she was seen here. She had several laugh lines in her speech, including one in which she said she wished the G.O.P. would say "that they feel so bad about the last eight years that they're just not going to run anybody for president. Somehow, I don't think that's going to happen."
