    In fact I don't think this is a "poll" at all. It's a self-selected panel of debate watchers. Only some of whom agreed to be called back and requestioned.
    It's not what would normally be called "self-selected," since the initial sample was selected at random. But with three chances to opt out (before the first interview, at the end, and when called for the second interview), it could be pretty darn messy.

    CNN should have consistently made clear that this was a panel study -- and one, I'm guessing, with such a high attrition rate that you might consider "panel study" a euphemism.

    I don't think it's a useless study. I think it's mildly interesting to reinterview people and see if the debate really made a difference to them. But portraying it as a sample of "registered voters who watched the debate," full stop, is wishful. And their SPECIAL NOTES OF CAUTION don't really help.

      the second problem then becomes obvious: if it's a panel study, then it's crucially important to know the baseline support/lean position of each respondent. Ideally, a panel like this should be evenly divided. But in this case, all we know is their fav/unfav opinions, and those were quite heavily skewed to Ryan. Another bit of info not provided with the initial CNN report, and not presented as a caveat in ANY mention of the poll results I've read so far. I can't see how this exercise has any value at all.

        I think it's mildly interesting that in both snap polls, the favorables hardly moved. So, I'm (mildly) glad they did the polls. And at least this time CNN made clear, or clear-ish, that the sample was probably off -- so if one found the more complete report and stared at it for a while, one wouldn't be too surprised by the CBS results. That said, the reporting was pretty useless, and the written report isn't a whole lot better.
