"Ceteris paribus or caeteris paribus is a Latin phrase meaning "other things equal"; English translations of the phrase include "all other things being equal" or "other things held constant" or "all else unchanged".
The 2020 election was unique so (eg) is this assumption valid "they tend to differ by about 1.8% for a population size around that number" ?
I too look forward to some more 2012 / 2016 / 2020 comparative analysis.
The real test will be when a Court examines and rules on these statistical findings.
Until then, it is all mere conjecture. It is tending (IMHO) towards over analysis of unknown source data and background variables.
(Believe it or not, I have taught economics to 4th year Mining Engineering students. My CP example was "take 27 variables, assume 25 are constant and graph the other 2".)
