This is pretty slick! Thanks! If you come back to this analysis in a later post, I'd love to see the trend in R^2 for this model over, say, years. I think this would get closer to directly evaluating the claim that this sort of model has been getting worse and worse at explaining variation in sentiment.

Another way to do this might be to use year dummies. (These might be collinear w the Trump dummy, though :/.) If the year-dummy coefficients aren't more or less significant in the past handful of years compared to the way-back-when years, then your hypothesis that the reduced form model is adequate for the post-pandemic years would be stronger, imo.

Thanks for actually crunching the numbers here! Good evidence that the answer for why Trump won is an answer that all partisans hate.
