Thats not the only problem of this poll. Looking through the crosstabs:
Corzine also leads 35-31-10 among Independents, while in almost every other poll Christie was ahead among Independents by 15-25.
So that poll is probably a crazy outlier.
Well, it may not be the 1-in-20 outlier so much as it may be a bad methodology outlier. Or it could just be the inflated number of "undecideds" will vote Republican in disproportionate number and that a more aggressive poll would have moved them toward Christie.
Whatever. It's probably not worth wasting too much time on this poll when there will be plenty of more reputable ones (including the intriguingly even-handed PPP) in the coming days.
PS: I'm still very interested in finding the best way to poll a race with a solid third-party candidate in it such as this one.
