In a sign that she may be losing ground in a state that should have been in the bag for her, Hillary Clinton is now polling under 50% in four different polls of New Jersey, a state that is right next door to her home base of New York, and shares a media market. The numbers:

Quinnipiac: Clinton 48%, Obama 43%

Strategic Vision (R): Clinton 47%, Obama 41%

Zogby: Clinton 43%, Obama 43%

Mason-Dixon: Clinton 47%, Obama 39%

New Jersey still has to be seen as leaning to Hillary, but Obama would pick up a fair share of delegates here if Hillary only has a narrow majority.
