This “Anglo-Saxon heritage” story sounded unbelievable from the get-go. An unnamed Romney foreign policy adviser allegedly told the London Telegraph that Romney would usher in better relations with the UK because he understands the “Anglo-Saxon heritage” better than President Obama — a oddly-phrased comment that clearly has racial undertones.

It’s usually a good idea to be skeptical of sensational-sounding Telegraph stories about U.S. politics in the first place, but this article literally relies on a single unnamed source — and yet Washington reporters ran with it anyway. Now the Romney campaign says the story is false, according to WaPo:

An unnamed “adviser” to Mitt Romney who told the London Telegraph that the candidate appreciates “Anglo-Saxon heritage” better than President Obama is not speaking for the Republican campaign, a spokeswoman for the former Massachusetts governor said Wednesday.

“It’s not true,” Amanda Hennenberg said in a statement. “If anyone said that, they weren’t reflecting the views of Governor Romney or anyone inside the campaign.”

The quote has created an early dust-up between the two campaigns as Romney begins his low-key, week-long trip through Britain, Poland and Israel.

“We are part of an Anglo-Saxon heritage,” an adviser told reporter Jon Swaine. “The White House didn’t fully appreciate the shared history we have.” The reporter later tweeted to clarify that the quote came from a “member of [Romney’s] foreign policy advisory team.”

Jen Rubin writes that the Obama campaign quickly began blasting the story out to reporters, which helped it go viral. It’s pretty clear the Obama campaign is scrambling to pump air into it. David Axelrod has been out front calling the “Anglo-Saxon” comment “unbelievably offensive.” Funny that a line Obama actually said himself is considered off-limits for criticism by his campaign, but an anonymous quote is fine to attack Romney.

WaPo also reports on the loose guidelines for anonymous quotes at the Telegraph:

Romney does have a team of 22 foreign policy and national security advisers, along with 15 working group chairs. British papers have looser guidelines on anonymous quotes than most of the American press. An “adviser” could have no actual role in the campaign; the Republican’s staff rarely talks to the foreign press.

The Telegraph in particular prints many rumors and blind quotes, often infuriating Democrats. “They use anonymous sources to a degree that makes you wonder if they actually have them,” consultant Bob Shrum told Dave Weigel in 2009.

Unless a reporter is able to verify who said this and what his role is in the campaign, Romney’s denial should put this story to rest.
