My gut feeling is there’s nothing in this world that will sway his core supporters. Those rabid mouth-breathing dumbass kool-aid drinking dipshits would disown their own children if they thought one of them voted for a democrat.
However, I think it could sway a lot of swing voters away from Trump. In American elections for POTUS, swing voters are extremely important.
Unfortunately, Biden is fucking up so bad on foreign policy (Gaza) that will lose Biden a lot of swing voters, too. Still anybody’s race is my guess.
This is just all my gut. It’s hard to trust polls anymore.
