The USA Today/Gallup Poll indicates 48 percent of Democrats interviewed would like the former vice president to run for president, which is 8 points lower than in a poll taken in March.

In the new poll, Gore finished behind Democratic presidential hopefuls Sens. Hillary Rodham Clinton of New York, and Barack Obama of Illinois, USA Today reported Tuesday.

Clinton for the first time won the support of 50 percent of Democrats and Democratic-leaning independents polled for the survey, and she commanded the most enthusiastic support of any candidate in either party.

Only once has a presidential hopeful received 50 percent support in a Gallup Poll and then lost a party's nomination and that was Sen. Edward Kennedy, D-Mass., in 1980, USA Today reported.
