No I haven't. I have heard of some of the type or kind of things he has said, but I haven't watch/listen to a recent interview or read one. Except… an excerpt of him about whether those with pre-existing conditions would be covered under the healthcare bill. I have largely stopped listening, as there was a lot of hot air, BS, and lies, coming from what he and his administration said, so I tried to focus on actions, not words. But that was probably also based on a presumption or wish that we wouldn't have to watch for signs of mental instability… (or that that would be fairly clearly distinguishable from their previous behaviour…). I can't imagine many 70 year olds go off the deep end when they had 70 previous years to do so (though there is dementia and other age-related cognitive declines). But this is also a 70 year old that has always been the boss, and has been in a multi-privileged bubble that has insulted him from dealing with criticism or reality. His veneer and image that he cares so much about is falling away before his eyes. He though this job would cement his puffed-up image he promotes of himself, but it is do the opposite. He believes (or has to believe others believe) that he is a winner, the best in near every category (he is the "most"/"best" of every positive attribute, according to him).
Hopefully you're wrong for all of our sakes, because one thing he has learned in the last 100 days is that military bombings result in support, and good media coverage….
