You realize how Presidential elections work, right? Because why you said makes no sense and is not the least bit correct.
You are voting for an elector. That elector is committed to the nominee of the party. If the nominee changes that is irrelevant. The elector still votes for the nominee.
I don't really buy that. While technically correct, you are voting for a particular nominee, in this case Biteme. It can't be assumed that all Biteme voters would have voted for a different nominee. Many may have voted third party, for Trump or not at all if it were another D candidate.
