Yes, the Rmoney campaign has denied it, but one of his surrogates just threw out a blatantly racist agitprop:

As the Republican presidential challenger accused Barack Obama of appeasing America’s enemies in his first foreign policy speech of the US general election campaign, advisers told The Daily Telegraph that he would abandon Mr Obama’s “Left-wing” coolness towards London.

In remarks that may prompt accusations of racial insensitivity, one suggested that Mr Romney was better placed to understand the depth of ties between the two countries than Mr Obama, whose father was from Africa.

“We are part of an Anglo-Saxon heritage, and he feels that the special relationship is special,” the adviser said of Mr Romney, adding: “The White House didn’t fully appreciate the shared history we have”.

Mr Romney on Wednesday embarks on an overseas tour of Britain, Israel and Poland designed to quash claims by Mr Obama’s team that he is a “novice” in foreign affairs. It comes four years after Mr Obama’s own landmark foreign tour, which attracted thousands of supporters.

(emphasis mine)

Romney promptly disavowed whoever said this, and the most likely suspect for this is a Heritage Foundation puke by the name of Nile Gardiner, (he has denied it) who is rather fond of the the phrase.
