Vermont Senator Bernie Sanders has erased Secretary of State Hillary Clinton's wide lead for the Democratic presidential nomination since the start of year, putting the two in a dead heat nationally, according to a Reuters/Ipsos poll.
Clinton leads Sanders 48 percent to 45 percent among Democratic voters, according to the poll of 512 Americans, conducted Feb. 2-5 following the Iowa caucus. The poll has a credibility interval of 5 percentage points.
Democrats had been supporting Clinton by more than a 2-to-1 margin at the beginning of the year. Sanders has narrowed that lead considerably over the past several weeks.
Clinton beat Sanders narrowly in the Iowa caucuses, the nation's first nomination contest ahead of the November election, but is expected to lose to him in New Hampshire. The two rivals clashed on Thursday night in their first one-on-one debate, reflecting the tightness of the race.
