I'm extremely optimistic right now, but there is one possibility that nobody is really talking about. What if Iowa is doing its own thing this election? It's possible for Iowa to be a tie AND Wisky to be a tie, as unlikely as that would seem in the abstract. After all, there are a few things about Iowa that distinguish it from other midwest states. One of them is that it's literally wedged between Tim Walz's childhood home and his political career. Walz is uniquely appealing in Iowa, I would think. Also, I would like to know how much money Trump is spending in NE-1, because Kamala has been spending money there and NE-1 ad spending bleeds into IA. It's possible that Kamala had a massive ad spending advantage in IA almost by accident.
Also, Selzer's technique isn't necessarily replicable. She has been doing this, and virtually nothing else political, for decades. She knows Iowa inside and out the way no national polling firm ever could. And it's a knowable state, because it's small in population, not diverse, not geographically cramped. It's not like trying to make sense out of South Florida or New York City (which, if NY was competitive, NYC would drive everyone mad), or Texas or even North Carolina.
