Well it does sort of go with the territory. If I am not mistaken, Ford loved the Chevy Chase "stumblebum" routine on SNL and had the clips played for him at the White House. Best thing a president can do is laugh that kind of stuff off.
Maybe that works for the Prez. As for me, when I see and hear the attack stuff, it makes me cringe.
It still hurt him. The irony that one of the most physically gifted of modern presidents, a first rate athlete, was portrayed as clumsy. Even Carter's collapse during a long run didn't get as much attention.
