Call from 202-759-1122. Caller id showed Voter Roll Call. Voicemail message in goofy, upbeat female voice: "You have been scientifically selected for a two-minute opinion survey on issues important to you and your neighbors. To start, press 1. This is the Voter Roll Call Opinion Research Company calling with a two-minute opinion survey on issues important to you and your neighbors. There is no cost. We do not need your name. And everything you tell us is confidential. To start, press 1."
Caller ID says "Voter Roll Call"
Message from a machine with a 2 minute opinion survey that is "no cost to you". I suspect a scam due to the last four words.
