There are signs of party unity among Democrats in Bergen County, which was deeply fractured last September during a Special Election for State Senator in the 37th district. Senator-elect Loretta Weinberg and Bergen County Democratic Chairman Joseph Ferriero were spotted dancing together on stage at a rally on Sunday featuring Illinois Senator Barack Obama. Jon Corzine, who backed Weinberg for the Senate against Ferriero’s choice, joined the party leader on a BCDO bus trip through South Bergen earlier today.
