I'm not quite sure if I can understand you, but in any case, yes, I was telling you that I wanted a candidate change before Biden's poor performance in the debate last week. And no, my mind isn't closed off to a candidate change, I was simply posting about the complexities of a candidate change, and used evidence (e.g., post-debate polling of [insert new candidate] versus Trump, which showed that any new candidate isn't likely to fair better than Biden)...just because I pointed out these complexities and used polling data to back it up, does not mean my mind is closed off to another candidate stepping in. I just think it is highly unlikely that one will (which is not an implicit endorsement of Biden staying in the race).
You aren't really capable of having an exchange because you treat every post as a battle-to-be-won and are more concerned with being right than with understanding nuance, complexity, or reality. It's tiresome.
