Based on polling conducted March 5-7, 2008
PRINCETON, NJ -- The latest Gallup Poll Daily tracking of national Democratic voters' presidential nomination preferences finds Hillary Clinton (46%) and Barack Obama (45%) in a virtual deadlock.
Clinton had held a 4-point advantage over Obama in each of the last three releases (March 2-4 through March 4-6). Obama moved closer after a more favorable showing Friday night. The two candidates have been in a tight battle in recent weeks. In only a few of the releases since Feb. 13-15 has either candidate enjoyed a statistically significant lead. The largest in either direction was an 8-point Obama advantage in Feb. 28-March 1 polling.
The candidates are battling Saturday in the Wyoming caucuses, and on Tuesday the Mississippi primary takes place. The next contest will be the crucial Pennsylvania primary on April 22. -- Jeff Jones
