Reckless and unwise: yes
stupidity: "lacking or marked by lack of intellectual acuity". He went to Harvard law school, stupid people don't do that.
And you think he is ugly just because he is losing his hair? What do you think of Patrick Stewart? Or Sean Connery? Michael Jordan? And besides that, what does his physical beauty have to do with anything in particular? I don't think that Bill Clinton is particularly attractive with his red face and really red nose, but the topic never comes up because it is totally besides the point (any point).
I would maintain that one can be smart in one area and stupid in another. At face value ... what he did was pretty fucking stupid.
