http://www.reuters.com/newsArticle.jhtml?type=topNews&storyID=6674749Bush led Kerry 48-47 percent in the latest three-day national tracking poll, well within the margin of error, setting up a tense final day in an extraordinarily close race for the White House.
Bush and Kerry were deadlocked at 48 percent on Sunday.
"Each candidate continues to do well among his base constituency," pollster John Zogby said. Only three percent of voters remain undecided.
Kerry was favored by young voters -- those between the ages of 18 and 29 -- by 64 percent to 35 percent, but the size of the turnout in that voting bloc is one of the biggest unknowns of Tuesday's election.
Zogby said he was calculating young voters would account for 12 percent of the total vote, but a larger share would be a boost for the Massachusetts senator. "Each point it goes higher translates into two-thirds of a percent for Kerry if these numbers hold up," Zogby said.
Kerry had a 54-40 percent edge among newly registered voters, another unpredictable group that could be a wild card on Tuesday depending on how many actually vote.
But Bush's strongest issue, national security and the war on terror, moved into second place on the list of most important issues to voters. The economy has been the top issue since the poll started on Oct. 7
Most of the three-day poll was conducted after a threatening new videotape from al Qaeda leader Osama bin Laden surfaced.
At this stage of the disputed 2000 election, Bush led Democrat Al Gore by one point in the daily tracking poll.
