In looking back at history - Reagan was clearly suffering the early stages of dementia during his last term. And yet - the country survived. My question regarding who is more 'fit' to govern is simple - Who is LESS likely to destroy the world my granddaughters will inherit? 45 might be less prone to dementia, but he's clearly suffering from untreated mental health issues and no one really is talking about that. If I have to choose between forgetfulness & tongue tied versus narcissistic ego-mania with no conscience for the consequences of their behavior - yeah - I'll take the older guy for $1000, Alex.
