I did once but it was actually a campaign call disguised as a poll. they were like, "on a scale of 1 to 5 how do you feel about the governor doing (this) or (that)", things like using a state trooper helicopter for personal business or something, and I assumed that they were going to loop around and ask similar questions about the other candidate, but they didn't.
The entire thing was just them telling me vaguely suspicious or corrupt things that the incumbent had done, but they phrased them as if they were questions and wanted my opinion to keep me on the phone and it worked
