Mitt Romney recently traveled abroad to try to demonstrate his foreign policy credentials, because we all know a few staged meetings with leaders of key U.S. allies is enough preparation to serve as president. Romney, however, was unable to pass even this extraordinarily easy test. Instead, his foreign trip served to reinforce what many people already believe about him -- that despite some strengths, he is an extremely bad candidate. This trip will be remembered more for Romney's insulting comments about the London Olympics and the quick and profane temper of his aid, Rick Gorka than for anything Romney did to demonstrate statesmanship or even an understanding of the world outside the U.S.
