Clinton 63% Trump 36%
To put it in perspective:
2012: Obama 58% Romney 40%
2008: Obama 57% McCain 41%
2004: Kerry 52% Bush 46%
Trump would lose traditionally Republican Somerset and Monmouth Counties, he'd barely win in Morris & Cape May Counties, both solid GOP counties (Chris Christie began his career as a Morris County Freeholder) he'd be destroyed in swing Burlington County, and he'd perform as well as past nominees in Hunterdon, Sussex, and Warren Counties - especially Sussex. He'd also under-perform in Western Essex County which is Republican. Keep in mind Chris Christie carried 19 of 21 counties in his re-election bid.
I agree as well. Trump would be absolutely demolished in New Jersey. Hillary Clinton might even win Morris and Cape May Counties.
