Illinois Sen. Barack Obama is closing on New York Sen. Hillary Clinton in the Pennsylvania Democratic primary, and now trails 50 to 44 percent among likely primary voters, according to a Quinnipiac University poll released this morning.
Sen. Clinton held a 50 to 41 percent lead in the April 2 poll.
In this latest survey, one of the biggest shifts is among women who went from 54 to 37 percent for Sen. Clinton April 2 to 54 to 41 percent for her today.
Other groups show:
• White voters for Sen. Clinton, 56 to 38 percent, down from 59 to 34 percent last week.
• Black voters back Sen. Obama, 75 to 17 percent, compared to 73 to 11 percent in the last poll.
• Men favor Sen. Obama, 48 to 44 percent, compared to a 46-46 tie last week.
• Voters younger than 45 go with Sen. Obama, 55 to 40 percent, while older voters back Sen. Clinton, 55 to 38 percent.
"With two weeks to go, Sen. Barack Obama is knocking on the door of a major political upset in the Pennsylvania Democratic primary," said Clay F. Richards, assistant director of the Quinnipiac University Polling Institute. "Obama is not only building on his own constituencies, but is taking away voters in Sen. Hillary Clinton's strongest areas -- whites including white women, voters in the key swing Philadelphia suburbs and those who say the economy is the most important issue in the campaign."
