Does Christie Win In NJ? Is There Still Some Reason For Optimism?

Here's one take from NRO's The Campaign Spot (Jim Geraghty):

[O]ne of my readers, who puts my number-crunching to shame, has been arguing throughout the campaign that Corzine's constistently abysmal favorability and job approval ratings make the most likely outcome a Christie win of 4 to 5 percentage points."

Sounds a bit optimistic for me . . . especially since not all of the livingly-challenged voters have been heard from yet (I hear that they usually split 110% D to 0% R).
