Denver, Colorado - Demanding equal pay for equal work and affordable health care for all, Senate women took the podium Tuesday at the Democratic convention to offer their support for Barack Obama's presidential campaign.

New York Senator Hillary Clinton, who narrowly lost the centre- left party's nomination to Obama, introduced the senators in a video appearance and is to make her own appeal for party unity later in the evening.

Denver, Colorado  - Senator Hillary Clinton, who brought her presidential bid within a hair's breadth of winning her party, was expected to appeal later Tuesday for her 18 million backers to get solidly behind rival Barack Obama in the general elections.

But ahead of the much-awaited speech before 4,400 Democratic Party delegates in Denver on Tuesday, many supporters continued to be unhappy about a prospect of forced unanimity and were trying to force a state-by-state roll-call vote the next evening.

Washington, Aug 25 : Hillary Clinton, the New York Senator, praised Barack Obama’s choice of Delaware Senator Joe Biden as the Democrat Vice Presidential candidate.

Clinton was responding to Republican candidate John McCain’s campaign that looked to exploit Obama’s selection of Biden over Clinton as his running mate.

As quoted in the CBS News/New York Times poll released Sunday, 42 percent of the delegates originally pledged to Clinton said they will vote for her on the convention’s presidential roll call. Fewer than half were enthusiastic about Obama’s nomination.

Washington, Aug 25 : Former New York Mayor Rudy Giuliani has voiced his sympathy for arch rival Senator Hillary Clinton, and said that the New York Senator would have been the obvious choice rather than Joe Biden as Democratic presidential candidate Barack Obama’s running mate.

“The strong choice would have been Hillary Clinton, the obvious choice would have been Hillary Clinton rather than Joe Biden as the running mate for Barack Obama,” Giuliani said.

“It''s kind of a no-brainer that that''s your ticket,” the Daily News quoted Giuliani, as saying.

Washington, Aug 25: Forty two percent of delegates pledged to Senator Hillary Clinton have said that they will for her at convention despite calls from Democratic leaders for party unit.

A CBS News/New York Times survey shows some continuing dissatisfaction among delegates pledged to Hillary Clinton. The dissatisfaction among Clinton delegates relates to both the nominee and the process by which he was elected.
