DENVER — Robin Young came to the Democratic national convention as a passionate Hillary Rodham Clinton supporter but says she is still unsure whether to vote for Barack Obama.

“What I do in the voting booth is my business,” said Young, 35, a rancher with her husband in Roanoke.

"I’m closer to an Obama supporter than I was when I got here," Young said after Clinton’s convention night speech in which she urged her supporters to back Mr. Obama. "But I’m still on the fence. I still have concerns about his experience."

Winning over those who went for Clinton in the Democratic primary fight is considered key to Obama’s chances in the fall against Republican John McCain.

For now, Young said she is looking for assurances from Obama that he will push an agenda as president that reflects “the struggles of women.”

If he does, then many disappointed Clinton supporters like her will rally behind him. If not, “it’s going to hurt a lot of people,” she said.

"I’m looking for more, and that’s going to have to come from Obama and the debates,’’ she said.

Young, an alternate delegate at her first convention, said she spent hours before the primary calling and e-mailing supporters in Denton County because she saw the New York senator as being the best qualified.

“Hillary just did the hardest campaign fight in her life,” Young said. “The Democratic Party means so much to her, and she’s done more to support Obama than probably anyone else.”

Young, the former mayor of Northlake, said it’s too early to tell whether Clinton supporters will switch to Obama, stay home or even vote for Republican John McCain.

“I know Obama is going to do everything he can,” she said. But Young said she’s not certain it will be enough.

For her part, Mrs. Young said she wants to focus on ensuring that her party continues pushing for expansion of health care and education improvements.

Also attending the convention for the first time is Amy Manuel, 43, of Denton, an alternate delegate for Obama. She predicted he not only will win the presidency but also carry Republican-leaning Texas.

“It’s time for something different... on every single one of the issues, [Obama] is right there with me,’’ said Manuel, database analyst.
