Gov. Jon Corzine, struggling to win a second term, seems to be getting Democrats back on his side. A Quinnipiac University poll released today has Corzine leading Republican Christopher Christie 83%-10% among Democrats. In a July poll, Corzine led Christie 76%-19%. Corzine’s electoral problems among Democrats became evident when the governor won just 77% in the June 2 Democratic primary against three challengers with no money, no base, no organization, and no name identification.
