On the eve of Mitt Romney's arrival in London, one of his advisers made a remark that The Telegraph says "may prompt accusations of racial insensitivity."

That's a fair assessment. When explaining why Romney would have a better grasp of the relationship between the United States and the U.K., the adviser had this to say—

We are part of an Anglo-Saxon heritage, and he feels that the special relationship is special. The White House didn't fully appreciate the shared history we have.

Obama, of course, has a different heritage, as his father was African.

This is only the latest dig at Obama's heritage by the Romney campaign.

Last week, Romney campaign co-chair John Sununu said Obama "has no idea how the American system functions, and we shouldn't be surprised about that, because he spent his early years in Hawaii smoking something, spent the next set of years in Indonesia, another set of years in Indonesia..."

Sununu later added, "I wish this President would learn how to be an American."
