@juddlegum Maybe it's time for media outlets to stop entrusting their elections coverage to math majors, and instead start consulting people who run or ran campaigns for a living?
The result of the mid-terms was not that surprising and was completely in-line with established polling houses' numbers in mid-October (when this headline was published) and beyond.
For example, This Sienna result from October 9-12 https://scri.siena.edu/wp-content/uploads/2022/10/US1022LV-Crosstabs.pdf showed an R+4 environment nationally and we ended up at ~R+3.4.
But what does that number, on its own, really tell you? Without context, almost nothing.
Does that number represent a significant change from a prior survey? Did the polling house weight the sample differently from previous surveys or from other pollsters (that could tell you they're thinking differently about the shape of the electorate)? Did the number precede/succeed a significant external event or a change in strategy/tactics?
That kind of context is best provided by folks who have had skin in the game. Ignoring the context in which a set of numbers was generated and simply reporting on a horse race does a huge disservice to those interested in politics, elections, and campaigns.
