Palmer Report’s analysis focused on the four states where Trump pulled off improbable surprise victories that went sharply against the polls, even as the rest of the nation largely fell in line with the polls. Those four states were Michigan, Wisconsin, Florida, and Pennsylvania. We documented how it was statistically suspicious that Trump pulled off all four of those upsets by the same 1% margin, while a more realistic statistical distribution would have had him winning one of the states by 0.5%, another by 3%, another 1%, and so on (link).
We documented how Hillary’s early voting lead in Florida should have been mathematically insurmountable on election day (link). We also documented other mathematical unlikelihoods about the results (link).
