Will believe the doctor or not?

So I have a question...after every Biden press conference or debate you have all the mean trump people calling him 'dementia joe' and talking about how they can see his dementia and blah blah blah. So after he gets his physical and mental evaluation at the start of his presidency and is declared competent in all ways will y'all finally believe it or not? Trump supporters believe his doctor who claimed "healthiest man ever and could live to be 200 yrs old" without batting an eye. So will you trump folk who claim he has dementia stop harping on it after he is cleared or won't the doctors opinion matter just because it is Biden.
