Both Democrats run about even with McCain
PRINCETON, NJ -- Gallup Poll Daily election tracking from March 14-16 finds Hillary Clinton's bid for the 2008 Democratic nomination supported by 47% of national Democratic voters, and Barack Obama's candidacy favored by 45%.
Obama led Clinton in all Gallup Poll Daily tracking reports from March 9 through March 16, indicating he had a real, albeit slim, advantage in national Democratic preferences over this period. While not statistically significant, Clinton's two percentage point advantage in today's report is a notable shift, particularly in light of the political storm Obama has faced over the past few days concerning controversial political statements made by the former pastor of his Chicago church.
Both Democrats run roughly even with John McCain in hypothetical trial heats for the fall election. But for the second consecutive Gallup report, McCain does slightly better against Obama than he does against Clinton. From March 12 through March 15, the two Democratic candidates' positions against McCain had been identical in Gallup Poll Daily tracking. -- Lydia Saad
