Mayor, then governor, better qualifications than Obama and McCain.
She was so busy doing her job as Governor, that she was not up on European International affairs. That was where she got hit the hardest, by the interviewers, and that is where she looked out of place. As Governor she did not deal with Europe she only dealt with the Pacific Rim nations. That was her weak point, but could have easily been overcome.
As Governor of Alaska she did have dealings with foreign nations, something most other Governors do not get the opportunity to do. Being geographically separated our dealings with Korea, Japan, Russia, and China are much more direct than in the lower 48. That is one area the interviewers stayed away from. They intentionally made her look bad.
