Until that breakdown you suggest actually is provided, I’d call BS on the poll itself.
If you’re going to go to that amount of work, and calling 50,000 people (actually a lot more to get 50k responses) is a hell of a lot of work. Thirteen people making calls...about 4,000 successful calls each...five minutes to reach a responding voter...twelve responses per hour...that’s over 300 hours per person...or seven weeks of full-time work...per person. Seven weeks. Double the calls per hour and it’s still almost a month of full-time work for all 13 people.
Anyone doing that much work would provide more information than the raw totals, especially with such stunning results. I call hoax.
Unless there are more clarification details coming, I tend to agree with your assessment. This guy says 13 people got it all done in two weeks.
