The salesmen come door to door to small businesses. (Two came to mine and they were quite persistent.) Their premise is that they just want you to conduct a survey. (In my case it was about illegal immigration.) The real purpose of the visit, though, is to get you to become a member. It is unclear what the benefits may be. I don't need them to write my congressman (or woman). However, the survey, and the premise of the office visit is a ruse.
