Sen. Clinton (D-N.Y.) has tried to erase any impression that she might be a sore loser by declaring repeatedly that Sen. Barack Obama (D-Ill.) has her full support and that her followers should do all they can to elect him. She spread word early in the week that she would ask her delegates to vote to nominate Obama for president at the roll call.

But many Clinton supporters don’t think the Obama crowd appears very grateful.

“I think it should be a two-way street,” said Kim Muller, a Clinton delegate from Oneonta, N.Y. “They asked us to put aside two years of hard work for Hillary.

“It would be nice if they reached out and said, ‘We recognize what you did’ and said thank you,” said Muller, the former mayor of Oneonta. “I don’t think they’ve done that.”

Fran Turner, a Clinton delegate from Onondaga County, questioned why no one from Obama’s campaign has spoken at a New York delegation breakfast to bring Clinton’s followers into the loop. The state delegations gather for breakfast each morning of the convention. Clinton addressed the New York delegation Monday morning.

Turner said Obama’s campaign “should be doing more to reach out to her supporters” and solicit their help.

“They’re depending on Hillary to do that; they should do that as well,” she said.

The Obama campaign did not respond to requests for comment.

Other Clinton delegates expressed even sharper frustrations with Obama’s camp.

“They’re the worst poor winners I’ve ever seen in my political career,” said Mary Sullivan, a Clinton delegate from Albany who has attended Democratic conventions in Chicago, Los Angeles and New York.

Sullivan said that Clinton delegates have done a lot to show their support for Obama but have received few gestures of gratitude.

“Clinton delegates can only go so far,” said Sullivan. “They need to meet us halfway.”

“The rift is still not healed,” said Sullivan, who sits on the international executive board of the American Federation of State, County and Municipal Employees (AFSCME).

Sullivan said that at an AFSCME meeting, pro-Clinton delegates introduced a resolution thanking Clinton for her political work and Obama supporters reacted against it strongly.

“You would have thought they put forth a resolution that said, ‘Hang Obama,’ ” said Sullivan, describing the intensity of the opposition to a resolution lauding Clinton.

These delegates are speaking out at a time when polls show that many Clinton supporters say they are reluctant to back Obama’s campaign. A recent poll showed that 20 percent of those who voted for Clinton in the Democratic primary say they will vote for Sen. John McCain (Ariz.), the expected Republican nominee, in the general election.

Even after losing the nomination, Clinton has kept the intense devotion of her supporters, more so than candidates who have fallen short in past primaries, such as former Sen. Bill Bradley (D-N.J.).

“All of us worked very hard for her and hold her in the highest possible regard,” said Rep. Tim Bishop (D), who represents Long Island.

Some Hillary supporters are also miffed that Obama’s vaunted money machine has not done more to retire Clinton’s massive debt.

Obama promised to help retire Clinton’s debt when the two camps negotiated her withdrawal from the Democratic primary. But Obama supporters have since done little to help Clinton pay it off.

A review of fundraising data compiled by the Federal Election Commission shows that Obama donors have given only $200,000 to Clinton’s presidential campaign to help retire her debt, which is estimated at more than $20 million.

Clinton supporters characterized the Obama debt relief as paltry.

“That’s relatively modest,” said Bishop.

“That’s a drop in the bucket,” said New York state Sen. Toby Ann Stavisky, another Clinton delegate.

Marcia Sullivan, an Obama delegate from Fort Edward, N.Y., said she has donated some money to help Clinton pay her bills.

But Sullivan said it is primarily Clinton’s responsibility to pay off her own debt, noting that she owes much of it to herself because she took out multimillion-dollar personal loans to fund her campaign.

“It’s up to her to retire her own debt,” said Sullivan.

Despite the grumbling, lawmakers who backed Clinton’s candidacy predict that her delegates will coalesce behind Obama on Thursday, when he expects to receive the nomination.

Rep. Debbie Wasserman Schultz (D-Fla.), one of Clinton’s staunchest allies, said that Clinton’s supporters won’t abandon the Democratic ticket this year, because they disagree with Republicans on the issues.

“Hillary Clinton’s supporters understand we can’t give away the Supreme Court because of Roe v. Wade and equal pay [for women],” she said.
