A majority of U.S. Democrats want presidential candidate Barack Obama to choose his rival Hillary Rodham Clinton as his running mate should he win the nomination, according to a poll released on Tuesday.

The new Gallup poll showed that 55 percent of 1,017 Democrats and Democratic-leaning independents surveyed believe Obama should share the "dream ticket" with Clinton if he wins in the presidential nomination race.

Among Clinton's supporters, nearly 75 percent want the New York senator to be offered the No. 2 spot, while only 43 percent of Obama's voters agree, said the poll.

The two candidates continue with their competition for the nominee to West Virginia on Tuesday as thousands of voters are casting their ballots across the state.

With only six primaries left before the nomination race ends, the Democratic Party still has no winning candidate.

However, about 55 percent of Democrats was ok with the continuing campaign while only 35 percent said Clinton should dropout, the same Gallup poll showed.

But there is a major difference in views of this issue between supporters of the two candidates. Three-quarters of Clinton's supporters insisted she should stay in the race, compared to 60 percent of Obama's supporters said she should quit, it added.

Despite Clinton's vow to stay until there is a Democratic presidential nominee, she was trailed by Obama in the latest national poll, at 50 percent to 44 percent, a separate Gallup poll showed.
