Hillary Clinton delegates may feel fuzzy and warm toward Barack Obama on Wednesday after a rousing "unity" speech by their candidate, but many are insistent they get the chance to cast their nomination vote for what could have been a history-making turn at cracking the glass ceiling.

"Obama has all the delegates he needs to win," said California delegate Paula Villescaz, who cast her vote for Clinton early in the day. She added that her vote was not in protest of Obama.

"Some Clinton supporters are trying to honor all the great work she did and all of her accomplishments," Villescaz said.

"The first ballot is needed to show the progress women have made," said Nikema Williams, a Georgia delegate who works for Planned Parenthood. "I want everyone to know how far women have come in the political process."

On Wednesday afternoon, Clinton, during a meeting with her supporters, released her delegates to vote for Obama, drawing shouts of "No!"

But her delegates cheered when she added that she's not telling them how to vote. Clinton, however, made it clear to them how she voted.

"I signed my ballot this morning for Sen. Obama," she said.

Clinton made an appeal to her supporters to back Obama during the closing speech of the convention's second night on Tuesday.

"I want you to ask yourselves: Were you in this campaign just for me?" Clinton asked. "Whether you voted for me, or voted for Barack, the time is now to unite as a single party with a single purpose."

To that end, Clinton will announce the Empire State's delegate total from the floor during the formal roll call vote conducted by House Speaker Nancy Pelosi, according to a senior Clinton adviser. The move is designed to further underscore Clinton's support for Obama.

And FOX News has confirmed that there will be no stoppage of the roll call and 50 states will "have their say."

Clinton delegates praised her speech, calling it "amazing" and "outstanding," yet several have said they won't budge until she gives them the signal, and it should come at the end of the first roll call.

"If we don't have an official roll call vote state-by-state, it is going to reopen a wound," said Sonja Jaquez Lewis, a Clinton delegate from Boulder County in Colorado.

Georgia delegate Beverly Leaphart said she plans to vote for Clinton until she is released. She said other delegates told her Wednesday morning that Clinton didn't do enough to unify the party.

"I think in the end, all Democrats have to make a decision on what they want in the next four years," she said. "Four more years of George Bush or four more years of change."

But Alabama Sen. Roger Bedford, who has supported Obama since Clinton conceded, said delegates who vote for Clinton at the convention are going against Clinton's wishes and the best interests of the party. He said he was casting his delegate vote for Obama.

"She unquestionably endorsed Obama" in her speech Tuesday night "and she asked us to support Obama," he said. "I do not want more four more years of Bush's failed policies. ... When it comes to this general election, it's time to do what Hillary asked us to do last night."

Williams said despite lingering desires for Clinton, Obama is going to be all the delegates' nominee.

"At the end, it will be a unanimous decision to endorse Obama," Williams said.
