PRINCETON, NJ -- For the fourth consecutive Gallup Poll Daily tracking report Barack Obama and Hillary Clinton are nearly tied in the preferences of national Democratic voters, earning 47% and 45% of the vote, respectively.
Today's results are based on interviews conducted March 21-22 and March 24, with no interviews conducted Easter Sunday, March 23.
While the Democrats' battle for delegates continues to be fought on a state-by-state basis, the national preferences of Democratic voters could be an important factor in whom the superdelegates to the Democratic National Convention this summer choose to support, and thus in the outcome of the race. At the moment, neither Obama nor Clinton has a significant edge. (To view the complete trend since Jan. 3, 2008, click here.)
For now, the November general election looks just as competitive as the Democratic nomination battle has become. In separate trial heats for president, John McCain's lead over both Democrats has narrowed to one percentage point. -- Lydia Saad
