I don't think an 8 point win nationally for Obama would translate into a 9 point NJ win but whatever...
a vast majority of the undecideds would/will break Obama. NJ Dems always have cold feet during the summer. such is life, bro.
I'm not sure if that's the case this time. This poll seems to have been run concurrently with the poll showing Zimmer behind Lautenberg by 1.
I'm guessing that New Jersey Democrats are solidly behind Obama, but not solidly behind Lautenberg (yet). I wouldn't expect Obama's numbers to swell in New Jersey too far beyond what they already are here.
Of course, since we can only see the toplines, who knows for sure.........
