I actually think Bill is in a really tough position. No one has ever had to play husband-to-a -presidential-candidate before. He can't really pull of the hug-children-and-wave trope of a presidential wife, but people freak out whenever he tries to act like a political advisor or partner. (Although, to be fair, they did that to Hillary when she was First Lady, too.)
Anyway, I'm not defending his behavior as good, I just think it must be hard for him to find the right line to walk.
