Democratic New Jersey Gov. Jon Corzine jumps to a 5-point lead in the latest Quinnipiac poll with a week to go until the election. He has trailed Republican challenger Chris Christie all year, but has spent liberally and also been aided by the independent candidacy of Steve Daggett. Even this poll shows the race to be fluid, because 38 percent of Daggett backers may change their minds before election day and their second choice is predominantly Christie. Rasmussen still has Christie up by three.
