PRINCETON, NJ -- The latest Gallup Poll Daily tracking shows Hillary Clinton with a five percentage point lead over Barack Obama in national Democratic voters' nomination preferences, 48% to 43%.
This marks the second consecutive day of Gallup Poll Daily tracking showing Clinton with a statistically significant lead over Obama, something she had not accomplished since Feb. 7-9 polling. Clinton's recent momentum has coincided with the controversy created by Obama's association with controversial preacher Rev. Jeremiah Wright.
Obama made a major speech on Tuesday addressing the race issue in large part to help move past the controversy. While Tuesday night polling showed no immediate benefit for Obama, the Wednesday results were more favorable to him, as reflected in the slight drop in Clinton's three-day average lead. This suggests at least the possibility that Obama has stopped his losses. The tracking data over the next several days will be a crucial indicator of the lasting impact, if any, of the Wright controversy.
Currently, registered voters express a slight preference for John McCain rather than either of the Democrats for the general presidential election. McCain has a 47% to 43% lead over Obama, and holds a 48% to 45% edge over Clinton. Both sets of numbers are unchanged from Wednesday's release. -- Jeff Jones
