Yes, they are. I had a conversation the other day with some workers that proved it to me. Took a bit to make them feel comfortable, but then they were overwhelmingly Trump.
There are zero Hillary signs or stickers in Joisey. Hell, I see way more Obama/Biden stickers on older cars. I am shocked at how vocal Trump supporters are. Barber shops are a great retreat for Trumpers. Everyone admits that they are not putting up lawn signs or stickers on their cars because of fear of retribution
