Pollsters putting their thumb on the scales for Democrats
Spencer touched on this New York Times analysis yesterday, which I think is quite interesting and speaks to at least some of the points I raised in my pre-Labor Day 'electoral lay of the land' post. Polling errors have not been unusual or infrequent in recent cycles, with most of the misses inflating Democrats' standing, compared to their actual vote share performance when the votes were counted. Some of the more infamous examples in the last few years were Florida's statewide polling in 2018 (both Rick Scott and Ron DeSantis were projected to lose, then both Republicans won), and Maine's 2020 Senate race:
The final ten public polls of the race averaged out to a lead of more than five percentage points for Susan Collins' Democratic challenger. Collins then won re-election by nearly nine percentage points. The polling average misfired by about 14 points. That's scandalously bad. The last six public polls in the South Carolina Senate race two years ago showed Lindsey Graham leading his opponent by less than two points, on average. In late September, one poll showed an exact tie; another showed Graham clinging to a one-point lead. Graham won his race by more than ten points. Similar patterns played out elsewhere. Nationally, we've made this observation about the 'generic ballot' back in 2021:
In 2020, the 'generic ballot' average predicted an expanded Democratic House majority, with Nancy Pelosi's team leading by nearly seven points. The actual margin? Less than half of that, enough of a difference to allow Republicans to sweep literally all of the House races rated by the Cook Political Report as 'toss-ups.......
There is more.
All the GOP needs to do is get a normal pickup in an off-year election and it will retake the House. Having an unpopular President actually leads to even bigger gains. The pollsters need to clean up their act to regain credibility.
