As of 1430 PST, Intrade has Corzine at 50.1%.
Here's my prediction: After the count, Christie 52%, Corzine 40%, Daggett 8%. Corzine appeals to the NJ Supreme Court on the grounds that the Democrat lost the election, therefore something was wrong with the vote counting.
The NJ Supreme Court concurs and orders a recount (remember, this is the same court which allowed Lautenberg to switch for Torecelli at the last minute).
After the recount, it is Christie 52%, Corzine 57%, Daggett 8%. Corzine wins!
Your post raises an interesting hypothetical point. We talk about being above the margin of fraud so that no recount could ever reverse the election.
The NJSC could, I suppose, find that the election was so bad—some wino testifies he was too drunk to find the polling place, for instance— they just throw the whole thing out and call a do-over for some distant date in the future. In the meantime, Corzine remains in power according to the NJ Constitution (as the NJSC interprets it “for the good of the public”)
