Minimal change, as only four states change sides in an election involving an incumbent President. It's typically three to five unless
(1) the incumbent is a catastrophic failure like Hoover in 1932 or Carter in 1980, or
(2) the incumbent is able to portray the opposing nominee as an unconventional and dangerous radical.
Five states and NE-02 changed hands between 2016 and 2020, and Trump had won so barely in 2016 that he could afford to lose only two.
I don't see Joe Biden as a disaster, and the GOP is already a far-right, semi-fascist Party to which Americans are well accustomed. Pence is more of the same that most Americans see in the GOP. Four states change hands, but Biden wins much as he did in 2020 in 2024.
The Red Scare rhetoric will fail in Florida the next time as it will be easy for Biden to distinguish himself from Raul Castro or Nicolas Maduro. Wisconsin is demographically similar to Iowa and goes with Iowa.
