As for Chappaquiddick, it made a difference of course. I think suppositions are just that, and just about worthless. Massachusetts loves the Kennedys, and there was an unspoken understanding (probably spoken a little I s'pose) that Teddy made a fine Senator, but would never be President.

He was not loved without reason.

Considering the outpourings of hagiography over President Reagan, the memorialization of Senator Ted is small potatoes.
