Unfortunately, the primaries are designed in a way that usually gives those people the candidacy.
Often, yes. However, the GOP apparatchiks are the most adaptive organization in American politics. They hate to lose, and they hate Obama at this point, as well. If they do well in the 2010 midterms, I could see them falling in line behind an "electable" candidate.
Who wants to try a bottle of merc's "Extroversion Olive Oil?"
But come on now...Clinton did a pretty fine job, and Obama is pulling his weight. No one is fully qualified for the presidency until they've actually become president anyway.
Clinton was better than Bush in many ways...I'll give you that. Although both were incompetent in their own ways when it came to military use overseas.
However, in the grand scheme of things, Bush sr was probably the last real president we had; an actual politician with considerable experience and competence in political affairs(Bush sr. for example was head of the CIA, so he was very much an inside man).
After that, now it just seems that being a boyish media personality counts more than actual competence. In the last election, political inexperience was actually seen as a positive rather than a negative. Since the 1930's or so(definately since JFK), the office of president has basically degenerated more and more into the office of America's #1 celebrity.
