Nothing wrong with family members being elected to office after another one serves, but the opinion that they are somehow elitists and deserve their turn is the problem. You see that in the democrats especially, but not so much in the republicans. Sorry, but I never felt that GW felt that we owed him the presidency because his father had been. Just because his brother Jeb has been bandied about as a running mate and possibility for 2012 while the primaries were budding doesn’t mean that any of them felt that they had it owed to them. Clinton does. In fact, Bill would like nothing better than to be able to run again. Hillary would feel she was owed the presidency. The Kennedys feel that they ARE the Camelot family. That they are the legitimate rulers in America. If there was ever a vote to return to having a king, for sure they’d think that their family is the ONE.
Nothing wrong with “family dynasties” in politics, in my opinion. As you’ve said, the real problem is when you have families in politics where the absolute best of them are abject mediocrities. The Kennedy family is a perfect case in point: JFK was the “best” of them but was one of the most mediocre presidents in U.S. history. With each succeeding generation they’ve gotten worse, and now we have mildly retarded members of that family who are considered capable elected leaders.
