Thomas Fitzgerald reports: A Quinnipiac University poll released this morning finds that Barack Obama has gained ground on Hillary Clinton in Pennsylvania.
Clinton leads 50 percent to 44 percent among likely Democratic primary voters in the survey, compared to 50 to 41 percent in a Quinnipiac survey April 2.
One of the biggest shifts in the latest survey was among women, a core Clinton constituency in the long nomination contest. Women favored the former first lady 54 to 37 percent last week, and 54 to 41 percent today.
"With two weeks to go, Barack Obama is knocking on the door of a major upset in the Pennsylvania Democratic primary," said Clay F. Richards, assistant director of the survey.
The poll was conducted April 3 through Sunday. Results are subject to a margin of error of plus or minus 3 percent.
