I got to knowing him fairly well and once gave him a lift after he had bike trouble. (We put the bike in the back of my pickup).
During the ride he mentioned that he used to work for one of the 2nd amendment organizations. He said one of their favorite tricks to raise money was a phony survey. They would have the person fill out a survey which would be sent to their local congressman.
Now they were honest in that they really would send the survey results, but the whole purpose of the mailing was raising cash. They would include a request for money to defray the cost of sending out the questionairre.
I have noticed the same sort of operation seems to be going on with the NRA as I have seen a few of those polls in Daddy's mail.
