>But I think in America this is not so much a matter of dynasty ( well, except for Kennedys ) as name recognition and celebrity.

not so sure - over here we have seldom politicians following parent/family footsteps,
much less than in your country, esp. if looking at lower level like gouvernor,
Mitt has that in his tree as well. Not done a real analysis - with more states to govern,
more such linkages have to show up, but I think there is a difference -
not sure if the election mode differences and upbringing explain all of them.
