I have been around a ton of people in my life and have had this conversation with many. I have yet to meet anyone that has ever been polled. I haven't even seen anyone online ever mention that they have been polled. I've frequented political forums for almost 20 years, almost daily, and have yet to read a single post of someone claiming they were polled.
I've been surveyed for product advertisment opinion, neilson ratings, all types of other useless shit, but not one time has anyone bothered to ask me who I support in an election.
