Time:  Clinton has a 6 point lead in PA, and adds:

One in five Pennsylvania Democrats has yet to pick a favorite candidate; and roughly one in six voters who told TIME they favor either Obama or Clinton said they could change their minds in the next two weeks. Notes Stanley Feldman, the SUNY Stonybrook political scientist who analyzed the poll for TIME, "Clinton’s six point lead over Obama at this point should not make her very comfortable. There is still plenty of opportunity for Obama to gain the voters he needs to win the Pennsylvania primary."

CNN:  Clinton has a 4 point lead in PA (down from 11 points last Friday)
