92% of ... A PRESIDENTIAL ELECTION.
This was a mid term replacement Senate seat.
It wouldn’t matter if he’d won or not, I’d still not believe that turnout.
Yes, I understand the difference between presidential and non-presidential years (and especially just a “special election” like this one which is not even a ballot with a lot of state and local races).
My point is simply that when someone gives a % of “voter turn-out” that generally means the percentage of registered voters who actually turned out to vote.
