Nate Silver's 2024 presidential forecast is now out. His initial probability is Trump with a 65.7% chance to win. That's similar to the Economist's model.
He's got Kennedy winning electoral votes in 5% of simulations. That seems impossibly bizarre. But fwiw the old FiveThirtyEight model had similarly long tails. I think it is just a byproduct of his conservative modeling.
He claims it is more or less like the old 538 model with some tweaks.
I mean there should be anxiety if the probabilities were flipped. This is going to be a close election. It was in 2016 and was in 2020. I would be skeptical if a model suggested anything else in either direction as nothing in the recent past elections, current polling, or fundamentals suggest otherwise.
