The details of a man or womans military service are not indicators of a quality executive. 60% of our US presidents have been members of the National Guard, yet that is only deemed unacceptable for a few Republican such as Dan Quayle and G. W. Bush.
The only person to become president with an unacceptable military record was "Worthless Willie" Clinton, who had his records altered and tampered with several times by his political allies. That is what you get in a state with one party rule, which Arkansas had for over 100 years.
