Well, it depends on exactly what goes down. That's always the answer.
What does this mean? Sounds like the sort of non-answer you'd expect from a politician. Either stand up and say you believe the Big Lie, or join the other Republicans here in accepting that the GOP can lose GA. Don't hedge. Giving a straight answer is better, even if your answer is 'no' (because then at least you're being honest about it and we can adjust our opinions of you accordingly).
A non-answer is the only correct answer to have right now, since we have not yet observed the election to know that it has been conducted fairly and legally. There are a practically infinite number of circumstances (whether favoring Democrats or Republicans) that could/should call into question the outcome of the election.
Giving a blanket "yes/no" answer at this point predicates your acceptance of the result entirely on its outcome, which is not what respect for elections and democracy entails at all.
