PRINCETON, NJ -- Barack Obama has edged up in the preferences of national Democratic voters, and now has a 48% to 44% advantage over Hillary Clinton.
Obama's four percentage point advantage in today's March 24-26 average is his largest in Gallup Poll Daily tracking since he led Clinton by 50% to 44% in the March 11-13 average. (To view the complete trend since Jan. 3, 2008, click here.)
Voters' preferences in two hypothetical November general election matchups remain close, with John McCain at 47% to Clinton's 44%, and McCain's 45% to Obama's 44%. The difference between McCain's 3-point advantage over Clinton as opposed to his 1-point advantage over Obama is not statistically significant, but marks one of the few times when the two races have not had either identical gaps or gaps only a point different. -- Frank Newport
