Obama's acuity is head and shoulders higher than that of his severe critics. The ones who scream the loudest about him do, indeed, appear batshit crazy. In the middle ground there are those who think little of some of his policy decisions--the TPP comes to mind as a large-scale risky deal--and there are some whose arguments have merits worht discussing. On the other extreme are those who idolise him--he has chartm, style, wit and courage, and he's good looking, I believe (not really being a judge of such things).

His wife has the same spectrum of detractors and admirers.

Perhaps the moral of this story is that it doesn't profit one to care much about simple opinion.
