PRINCETON, NJ -- Barack Obama and Hillary Clinton are roughly tied in national Democratic preferences -- 47% for Obama vs. 45% for Clinton -- according to Gallup Poll Daily tracking conducted March 6-8.
Support lines for the two Democratic contestants have now switched since Gallup's March 7 report, and Obama is back on top, although his two percentage point lead is not statistically significant.
Clinton gained on Obama in the days leading up to last week's March 4 primary voting, but her successful showing -- winning three of the four elections held that day -- failed to boost her candidacy nationally.
Obama had a solid victory in Saturday's Wyoming caucuses, winning 61% of the vote and more than half of the delegates. Any impact this might have on national Democratic preferences will not enter the three-day rolling averages in Gallup Poll Daily tracking until Monday's report. -- Lydia Saad
