I can attest to this. My FIL has dementia and at this point he is pretty laid back, but there was a time not even a year ago when he was still cognizant enough to *think* he could function normally but the reality was he was not able make good decisions at all. He had these exact kinds of outbursts Biden has and even in the outburst he often didn’t make sense nor could he formulate an argument. He blamed everyone for things missing, when he was misplacing them, was making a mess out of finances and taxes and arguing he was doing a good job, would get lost and argue he was not lost... Many of Biden’s behaviors remind me of that - I do not believe he is the one making the decisions but his defensiveness is so dementia-like. Just my .02
You know of what you speak, have had exactly the same experiences with a loved one as they progressed in “the long goodbye.”
This is truly a dangerous situation we are in.
