I actually think Hugin will win this one.
Why? Serious question. Iirc, undecideds break overwhelmingly Democratic in New Jersey, and I think Democrats tend to under poll compared to their actual results somewhat, though not to the same extent as say Nevada.
Personally, I am possibly by the skin of my teeth supporting menendez's reelection for the same reason that George will argue in his editorial calling for the Democrats to take over Congress as a desperately desperately needed restraint on Trump. That I knew nothing about his opponent. Frankly, if I felt confident of Democrats otherwise picking up 52 seats, I could live with Menendez going down. I would rather II as a second alternative indicted in forced to resign ASAP.
