Well, from what people have written in, it looks as though CNN and USA Today did suppress the results of their own gay marriage poll. Nobody’s been able to find a report on this poll from either CNN or USA Today. Poll expert Gerry Daly is not sure whether the poll can be treated as definitive or not. But he does suspect that a similar poll would have been touted by the media if the results had shown a strong uptick in favor of gay marriage, instead of a shift against it.

Apparently, when a poll shows a significant shift in public opinion, media outlets can either treat it as a big story, or dismiss it as a fluke. That leaves plenty of room for bias. But I suspect this case is even worse than Daly thinks. I doubt the folks at CNN or USA Today bothered to rationalize suppression of their own poll with Daly’s statistical argument. My guess is that they simply saw the results and knew that a story would have helped the side they were rooting against. Either way, this looks to me like an egregious case of media bias.
