Mr Moderate
The times Menendez started pulling away were also around the same time that Corzine increased on his lead in 05, same with Kerry in 04 (remember the close polls) and Gore in 2000. the state has had a long history of polling more Republican than it has actually voted and the polls have generally started to turn around and closer to the final result in the last couple weeks. Kean didn't lose due to Foley, it was just the earlier polls showed things better for the GOp than it actually was, it happens almost every year.
Yeah, New Jersey is like Germany in polling. Simply put, its right wing upper middle class minority is just very politicised and never undecided in polls no matter how far out of election day, leading to polls out of election season, especially ones that try to wean out weak leaners, to be more of an exercise in hilarity than anything else.
