It didn't seem to make much difference when the USA was led by a sex addict, Kennedy or Clinton.
Forgive my ignorance but what does being a 'sex addict' have to do with competence in foreign affairs?
While I believe that John McCain is an impressive Republican candidate I think his choice of running mate is pretty sad. Chosen purely for her appeal to ignorant red-neck types while trying to corner the womens vote at the same time... Not for any skilled handling of Alaska. Seriously sad stuff.\
I mean Arnie is the governor of an economic powerhouse vastly more important than Alaska and has even been re-elected - that doesn't mean he is competent. It might mean his advisors/public servants are, but my personal opinion is that is not even correct.
