Episode 11

The polls had Abdul El-Sayed cruising by 15-plus points in the Michigan Democratic Senate Primary. He won by one. This week we dig into one of the worst polling misses in recent history and what to take from it.

In this episode, we cover:

How did Michigan's Senate primary polls fool almost everyone? – El-Sayed edged Haley Stevens by a single point while polls and prediction markets had him winning by a much larger margin. Plus, Mallory McMorrow, already out of the race, still pulled 4%. We break down why the polls showed a blowout, the role of open-primaries and seasonality in polling, and whether pollsters herded toward the Emerson numbers.
Texas and Wisconsin are closer than the headlines suggest – A new YouGov poll puts James Talarico up on Ken Paxton, but Randy calls Talarico's lead "fool's gold." We analyze the 2018 Cruz-Beto comparison, the money gap, and why Mark thinks Wisconsin's Democratic primary between Francesca Hong and David Crowley is far from settled.
Maine, hot takes, and a sleeper Senate race – Troy Jackson leads Susan Collins in fresh Hart Research numbers, and we explain why we still wouldn't bet against Collins. Plus Randy's case that summer generic-ballot polls are overstating Democratic support, and Mark's pick for the race nobody's talking about.
