DeSantis only needs to win Arizona, Georgia and Wisconsin to become President. That's actually easy to do when you consider the margins Biden beat Trump by in those states and that was contributed to Republicans and Independents voting for Biden. That same group of people would vote DeSantis over Biden because they are idiots think think DeSantis isn't dangerous. I think he can beat Biden in Nevada and Pennsylvania too but I'll leave that off.
Also, Dems are losing 3 electorial votes from the 2020 map to the 2024 map. Some states gained a vote, others lost a vote. Republicans are gaining 3 electoral votes from the 2020 map to the 2024 map.
