Murphy will win this in a landslide, IMO
The only thing that could change that is a Sanders endorsement for Wisniewski.
A Sanders endorsement would be interesting and could upend things, but Sanders only won 35% of the vote in the primary last June. While I like Wisniewski more than Murphy, I think the establishment means a lot in the state, and Murphy has the whole establishment behind him at this point.
That was only because the DNC rigged it for Hillary, you see /s
Didn't Bernie skip campaigning in NJ so that he could focus on CA over that last week? That would be partly to blame for the particularly poor performance. But yes, NJ is very establishment, and he basically had no chance of winning it anyway.
