In my view, Mitt Romney like Sarah Palin before him, has demonstrated he's not fit to be the President of the United States. His recent silliness in London has shown him to be incapable of functioning as a competent human being beyond the narrow, and frankly stupid, base of the Republican Party's faithful. If at this stage of his life, the Twit is unable to open his mouth without putting both feet in it it is certain that he will not be able to serve his country beyond its borders.
So irrational, indeed insane, is the Republican Party that outside of the US its leaders are unable to function. They are truly buffoons, clowns who have no place the world stage.
