I've received three calls (all unanswered) from this number in the last 24 hours. Whoever the hell they are, they are persistent. Now that I've read what people here are saying about it, I'm going to block the number since I don't feel like ever seeing it again.
It's from a right-wing organization, it's a push-poll. They used several obvious dog-whistle phrases throughout the call. If you're a liberal or moderate, you should answer the questions to skew the results to make the survey useless to them.
