I called the number to see what I could find out, and they answered Stockton College, and I asked why they would be calling me at 8:30 pm when I have no affiliation to the college and he informed me that it was a poll being taken for the election.
Claims to be polling service from the Stockton College in NJ (Hughes Center for Public Policy in their Office of External Affairs). TRY calling 609-626-3542 to have your number removed. I suspect they obtained some numbers through the Hilton Hotel chain. Stockton College Risk Management office = 609-652-4693.
