PRINCETON, NJ -- Barack Obama has now cut the gap with Hillary Clinton to 6 percentage points among Democrats nationally in the Gallup Poll Daily tracking three-day average, and interviewing conducted Tuesday night shows the gap between the two candidates is within a few points. Obama's position has been strengthening on a day-by-day basis. As recently as Jan. 18-20, Clinton led Obama by 20 points. Today's Gallup Poll Daily tracking is based on interviews conducted Jan. 27-29, all after Obama's overwhelming victory in South Carolina on Saturday. Two out of the three nights interviewing were conducted after the high-visibility endorsement of Obama by Sen. Edward Kennedy and his niece Caroline Kennedy.
Clinton's lead in the three-day average is now 42% to Obama's 36%. John Edwards, who dropped out of the race today after Gallup conducted these interviews, ended his quest for the presidency with 12% support. Wednesday night's interviewing will reflect the distribution of the vote choice of former Edwards' supporters as well as the impact, if any, of Hillary Clinton's popular vote win in Florida on Tuesday.
These national numbers are a critically important indicator of the political environment when voters in more than 20 states go to the polls next Tuesday. At the moment, Obama has the momentum among Democrats nationally.
