  •  Off-cycle and special election? (0+ / 0-)

    While I certainly appreciate you bringing data to the mix, those are pretty edge cases.  If you'll recall, NY-23 was the one where the Republican dropped out like 3 days before the election and then endorsed the Democrat, and the 2009 elections were in an off-year where the turnout percentages are usually really messed up, and you're likely to have issues with a good likely voter screen (that election day wound up being less Democrat-unfriendly than most anticipated).

    Further, the NY-23 case is already in Mr. Silver's scoring system, and is a non-trivial factor in PPP's above-average score already.

    I'm not saying we should excuse those errors, but I don't see why they should outweigh Nate's analysis of their whole recent history.

    •  I'm focused on internals, not the topline... (0+ / 0-)

      ...numbers for these examples.

      The internals of their polls are screwy. Their weird sampling results in inaccurate secondary questions and approval/favorable numbers.

      Since the 2008 election, we have only been presented with 3 cases to judge the accuracy of pollsters: NJ-Gov, NJ-Gov and the special election in NY-23.

      In all three cases PPP failed miserably when looking at the internal numbers--especially with regards to approval/favorable numbers.

      I don't trust PPP because they haven't proven themselves to be a reliable pollster. A lot of that probably has to do with them being an automated pollster, but that's still no excuse for being so wrong.

      •  I don't know about that. (0+ / 0-)

        First of all, I don't know that there's any reason to believe that the exit poll favorability numbers are more or less accurate than the pre-election polling favorability numbers.

        You seem to be hyper-focused on personally disagreeing with unverifiable internals, and ignoring the verifiable final horse race numbers.

        •  You seem to forget all the fuss that was made... (0+ / 0-)

          ...leading up to those 2009 races about how it was a "referendum on President Obama", "a check on his presidency", etc., etc.

          The actual polling showed he had little or no influence on the election and was still rather liked by the voting public. In fact, the VA-Gov electorate was made up of McCain +8 voters and yet the President still achieved a 48% approval rating among them.

          The media rarely focuses on the topline number because the internals are more fun for them to play around with. That leads to BS CW thinking which turns out to be very wrong come election time.

          PPP has been doing it a lot recently. In fact, they have a recent post on their site claiming the reason Democrats are down in swing states is because of the President.

          How do they claim that? Well, their approval numbers for the President are low in those states so Dem deficits must be all his fault, no?

          They claimed the same thing with the NY-23 race and were proven wrong. They had the President's approval at just 39% in the CD (he won it by 8 points in E2008--51/43).

          •  fact check (0+ / 0-)

            Here's what Jensen actually wrote:

            Obama won all of these states in 2008 but his unpopularity in them now is a major contributor to the problems Democratic candidates are having in them this year.

            I'm inclined to disagree with that for a couple of reasons (the most important may be that Jensen doesn't even mention economic conditions). But as unsupported as "a major contributor" is, it doesn't equal "the reason" or "all his fault."
