2024’s spread is almost identical to 2020’s. just without Florida(which was still considered a swing state then). 2016 was a broad year with something like a dozen states considered gettable, and a couple states that ended up flipping weren’t even supposed to be swing states. 2012 only had a handful, I think even fewer than we have now, like 4 or 5. 2008 was another broad year.

Only way it can change is either if a swing state tilts hard enough to no longer be one(Michigan being too blue) , or a formerly safe state tilts enough to be up for grabs again(something like Virginia or Texas)
