I have the impression that Joe Kennedy wanted his children to be Slytherins who act like Gryffindors - to seem honest and brave and full of competitive vigor, but be willing to cheat if necessary to win.

It's amazing those kids turned out as well as they did.

And I think you have a good point about JFK. "The best and the brightest" is SUCH a Ravenclaw formulation.

Would Ted Kennedy be a Hufflepuff? Or was he Gryffindor too?
