Based on polling conducted March 7-9, 2008
PRINCETON, NJ -- Forty-nine percent of Democratic voters nationally support Barack Obama for the Democratic nomination compared with 44% backing Hillary Clinton, giving Obama a slight but statistically significant five percentage point lead.
For the past week Clinton and Obama had been neck and neck in national Democratic support, but preferences have now returned to where they stood in late February when Gallup Poll Daily tracking found Obama consistently ahead by a 5- to 8-point margin.
This comeback for Obama started prior to his victory in the Wyoming caucuses on Saturday, March 8, thus blunting Clinton's winning streak coming off of the March 4 primaries. Obama has led Clinton on each of the individual days included in today's three-day rolling average, from March 7-9. -- Lydia Saad
