The poll also found that they are more likely to say the war in Iraq is heading to a successful conclusion.
The poll offers a snapshot of a group whose energy and idealism have always been as alluring to politicians as its scattered focus and shifting interests have been frustrating. It found that substantially more Americans ages 17 to 29 than four years ago are paying attention to the presidential race. But they appeared to be really familiar with only two of the candidates, Senators Barack Obama and Hillary Rodham Clinton, both Democrats.
More than half of Americans ages 17 to 29 - 54 percent - say they intend to vote for a Democrat for president in 2008. They share with the public at large a negative view of President Bush, who has a 28 percent approval rating with this group, and of the Republican Party. They hold a markedly more positive view of Democrats than they do of Republicans.
28 percent described themselves as liberal, compared with 20 percent of the nation at large. And 27 percent called themselves conservative, compared with 32 percent of the general public.
Forty-four percent said they believed that same-sex couples should be permitted to get married, compared with 28 percent of the public at large. They are more likely than their elders to support the legalization of possession of small amounts of marijuana.
The findings on gay marriage were reminiscent of an exit poll on Election Day 2004: 41 percent of 18-to-29-year-old voters said gay couples should be permitted to legally marry, according to the exit poll.
In the current poll, 62 percent said they would support a universal, government-sponsored national health care insurance program; 47 percent of the general public holds that view. And 30 percent said that "Americans should always welcome new immigrants," while 24 percent of the general public holds that view.
Their views on abortion mirror those of the public at large: 24 percent said it should not be permitted at all, while 38 percent said it should be made available but with greater restrictions. Thirty-seven percent said it should be generally available.
In one potential sign of shifting attitudes, respondents, by overwhelming margins, said they believed that the nation was prepared to elect as president a woman, a black person or someone who admitted to having used marijuana. But they said that they did not believe Americans would elect someone who had used cocaine or someone who was a Mormon.
Mr. Obama has suggested that he used cocaine as a young man. Mitt Romney, the former governor of Massachusetts and a candidate for the Republican nomination, is a Mormon.
By a 52 to 36 majority, young Americans say that Democrats, rather than Republicans, come closer to sharing their moral values, while 58 percent said they had a favorable view of the Democratic Party, and 38 percent said they had a favorable view of Republicans.
Asked if they were enthusiastic about any of the candidates running for president, 18 percent named Mr. Obama, of Illinois, and 17 percent named Mrs. Clinton, of New York. Those two were followed by Rudolph W. Giuliani, a Republican, who was named by just 4 percent of the respondents.
The survey also found that 42 percent of young Americans thought it was likely or very likely that the nation would reinstate a military draft over the next few years - and two-thirds said they thought the Republican Party was more likely to do so. And 87 percent of respondents said they opposed a draft.
But when it came to the war, young Americans were more optimistic about the outcome than was the population as whole. Fifty-one percent said the United States was very or somewhat likely to succeed in Iraq, compared with 45 percent among all adults.Contrary to conventional wisdom, younger Americans have historically been more likely than the population as a whole to be supportive of what a president is doing in a time of war, as they were in Korea and Vietnam, polls have shown.
