We went late into the evening waiting for absentee ballots in Milwaukee County last night. But Milwaukee County executive David Crowley will become the Democratic nominee for governor in Wisconsin, despite it seeming like a certainty that Francesca Hong would be the winner. As of yesterday, every recent poll had shown Hong at least 20 points ahead. The two most recent public polls had her 22 and 25 points ahead. (The most recent poll from Crowley’s own camp showed Hong 19 points ahead!) We’ll come back to the question of why these polls have been so wildly off. But there was a different casualty from the night’s results that I personally enjoyed witnessing because it’s a hobbyhorse or pet peeve of mine — and it seems to be as well of the numbers crunchers/data nerds whose Twitter feeds I watch on elections night. I’m talking here about the “prediction markets.”
