Rumor-
This so-called "poll" is fatally flawed. It was an email poll to the newspapers subscribers. It has zero probability of being correct and statistically incoherent.
1. Where did you hear the rumour?
2. Is there actually any, you know, evidence, to back the rumour up?
I THINK this is a misunderstanding based on a badly written sentence in the original article. I think the article says that the result of a Mason-Dixon poll was e-mailed out to the newspaper's subscribers in advance, but that people are misinterpreting this as saying that the poll was conducted via e-mail to subscribers.
