The Gallup Poll conducted March 27-29 with a margin of error of 3 percentage points shows the Illinois Senator has a 10 point lead over the New York Senator among Democrats, marking the first time since early February Gallup polls have shown either candidate with a double digit lead. In February, Gallup showed Clinton held an 11 percent advantage over Obama.
Last week’s Pew Poll also confirmed Obama had weathered the media storm surrounding the Reverend Wright controversy and maintained his lead.
Despite pressure from some powerful Obama supporters and being behind nationally in the polls, Clinton said the race should not end before all votes had been cast. "I didn't think we believed that in America. I thought we of all people knew how important it was to give everyone a chance to have their voices heard and their votes counted," she said.
Looking to the critical state of Pennsylvania, Clinton holds a 12 percent lead ahead of the state’s April 22 primary, according to the latest CNN/Opinion Research Corporation poll released earlier this month.Both candidates continue to campaign heavily in the state of Pennsylvania Monday, where there are 158 pledged delegates up for grabs.
Update: CNN poll of polls released Monday, which includes the results of several recent major surveys, shows Hillary Clinton with a 14 percent lead in Pennsylvania over Barack Obama.
Update II: The latest Gallup tracking poll out Monday afternoon has Obama up by 8 points.
