Do they really think they have a chance?

PolitickerNJ reports:

There are now two Democrats who say they will challenge Jon Corzine in the Democratic gubernatorial primary in June: former Glen Ridge Mayor Carl Bergmanson and Perth Amboy Councilman Ken Balut. So far, neither seems to pose a real threat to the incumbent, who despite struggling approval numbers still has a 66%-24% job approval rating among Democrats. Bergmanson and Balut have not raised money or announced any endorsements.
