President Bush hasn't had a drink for how many years? I don't know everything the Bush girls have done, but college kids trying to buy a margarita with dinner at a Mexican restaurant somehow doesn't strike me as "boozed out" (more like stupid), and this ONE daughter of Jeb Bush's may simply be one of many individuals with an out-of-control anxiety problem. I don't see any reason to exaggerate.
Ronald Reagan had a couple of goofball kids, too. How much did it really reflect on him?
That's okay, some of them are demorats so that makes them okay to speak out on politics (even after posing nekid in Playboy, etc.).
