If he drops out for any reason he will blame America and say that he can't count on a fair election, whether in the primary or the general.
The thing is when it comes down to it will GOP voters really pick DeSantis over him? I don't know.
Depends on how tired of losing they get. We'll see what happens in Georgia tomorrow. If Warnock wins then Trump will likely take the blame again for that one, but if Walker wins then that's a big wild card.
IDK, if you haven't abandoned Trump after November 8th, I don't see why the Georgia runoff would be the final straw. You either blame Trump for the midterms or you don't.
