Wait, I don't understand, are you actually being insulting or do you actually think Obama's "stupid"? I mean, I get that you don't like the guy (for, uh, various reasons) but you don't become President of the Harvard Law Review and graduate magna cum laude if you're an idiot.
I think he
believes stupid things and as a consequence he
says stupid things -- the things he actually believes -- when TOTUS isn't there to stop him. (Oftentimes, when he "goes rogue" he does say factually incorrect things, which is a sign of ignorance more than stupidity, I'd say.)
Does that mean I think he's stupid? I've always thought that he shows, like a lot of college faculty, a combination of ignorance and arrogance that is dangerous. Compare him with, say, former-Pres. Clinton. Very few people would claim that Clinton is humble, but neither would many say he is ignorant. True, as President the man couldn't get out of bed in the morning before making at least two false statements but, unlike Obama, you never got the sense that he really thought they were true.
[modify:] Also, regarding the Harvard Law Review, don't get confused between the positions of "president" and "editor". The "president" is a figurehead, nothing else, while an "editor" is a "really sharp law student".
Regarding anything else that happened at Harvard, I don't know enough to comment because Obama won't release his records.
