I'm not sure I agree with your assumptions here. It seems like you're assuming that the Rs in GA somehow need Trump's direct support in order to win those seats? If that's the case, I don't think that necessarily holds. There are a lot of states in the US this election that went to Biden, but who seated a lot of Republicans. To me, that indicates that a lot of people in general still view Republicans as favorable to Democrats, but view Trump specifically as a bad egg that needs to go. My inference could be wrong, but if that's the case, I'm not sure that Trump's emotional state really has any material effect on those run-offs in GA. I think you're giving him too much credit.
