Historians aren't scientists anyway and I was just being a smart ass. I think he has some strong points, but it's worth noting that the average weighted polls have been more right than wrong over that time period too. And the 2022 election cycle was seen as the most valid and reliable set of polling data to date.
I'm not one who thinks stats tell the whole story and they can often be used to mask the reality. But they're a pretty good indicator of general trends, if not predictions. Adding more to get a full picture is needed since polls are static snapshots and rely on how the questions are worded. You can't really factor in something like the effect that foreign interference will have on an election, for instance. But someone's feelings are never a good thing to base any of this on. There are more kinds of data than just stats. Historians usually draw from that larger barrel, which is a good thing, even if I think using it to predict is foolhardy.
