“I wonder how Obama has a 50% unfavorable rating yet still gets 48% of the vote.”
Sure makes one wonder. It might be the weighting of the sample is wrong. If so, Mitt would probably be a couple of points higher going by the 50% unfavorable rating Obama got.
I don’t think PPP weights their polls, I think they just go by whatever the random sample of the respondents ends up being. Maybe Ds are more easily contacted in their samples, or more likely to finish the polling process, or there’s less Rs these days. Who knows.
