Hate to say it,  but I'm afraid dementia is going to come into play whomever wins the next election if it is a Trump/Biden race. Have known a few people with dementia and currently do that are close to me. One thing I've noticed that they all had/have in common is that kinda glazed over look in their eyes. Biden did already when he was running for President and you look at Trumps eyes back just when he was President , and take a look at them now. They've changed, and I'm not a doctor, but I think it is a tell tale sign of whats to come
