Democrat Barack Obama has pulled into a virtual dead heat with Hillary Clinton in New Hampshire two days before the state's presidential nominating contest, according to a Reuters/C-SPAN/Zogby poll released today.
Republican rivals Mitt Romney and John McCain are also essentially deadlocked as the White House races in both parties tightened ahead of Tuesday's New Hampshire primary.
About half of the polling in the four-day tracking survey was conducted after the Iowa caucuses last Thursday, when Obama and Republican Mike Huckabee sailed to easy wins in the opening test of the US presidential campaign.
Obama, an Illinois senator vying to be the first black president in US history, pulled within one point of Clinton in the state's Democratic race - a statistically insignificant lead. The poll in both races had a 3.4 percentage point margin of error.
Clinton, a New York senator and former first lady, led Obama 31 per cent to 30 per cent, with former North Carolina senator John Edwards at 20 per cent. Before Iowa's caucuses, Clinton led Obama by six points.
"We are seeing clear movement in Obama's direction and away from Hillary Clinton," pollster John Zogby said. "There isn't much time for her to regroup here."
Romney, the former Massachusetts governor who lost in Iowa to Huckabee, gained two percentage points overnight to move ahead of McCain by one point, 32 per cent to 31 per cent, also well within the margin of error.
Huckabee, a Baptist minister and former Arkansas governor, was in third with 12 per cent.
