Oh, I doubt that. After all, you have stated the "choice for potus is indeed a binary choice".
All that would have to be done is convince you that Trump is less evil than the other candidate of the "binary pair". Given your stated position, I expect you would then vote for him. Perhaps you would rationalize the action claiming it a "vote for the "lesser evil"; be it a vote for evil nonetheless.
This is the rationalization I expect most Trump supporters to have. I've stopped playing the "lesser of two evils" game.
