This has been a bad year for dreams of dynasties. The Bush dynasty has been dismantled with Jeb, who was the first favored son, writing finis to the family dream of a trifecta. Hillary Clinton, who started plotting her path to 1600 Pennsylvania Ave. when she was a law student at Yale, took a detour through Arkansas and if she still wants to be a president will have to settle for Wellesley, or Smith or one of the other Seven Sisters. But it won’t be anything in Arkansas.
