On the whole "Anglo-Saxon heritage" controversy:
No, it was a bit more than Romney's advisors just stating that the US shared Anglo-Saxon heritage with Great Britain. Virtually every credible mainstream historian in the United States would agree with that sort of statement. The Obama Campaign, as low as I found their tactics throughout the general election, were not completely baseless in pouncing on Romney for some of the statements made in the UK:
Given that it was a presidential election Team Obama could've written a book on this one quote passage alone. It really falls into the "anti-colonialist Kenyan" trope that conservatives were using on and off during Obama's first term.
And really, that was what the huge issue people had with Romney: he and his team seemed to think of every moment of the campaign as a good time to attack the president. Did not matter if it was the Olympics, if it was the attack on the consulate in Benghazi, Hurricane Sandy, the weather outside, how good the Cowboys will do this year, etc etc etc.. He might have ran an aggressive campaign (nothing really wrong with that) but he seemed to go as far if not further to attack Obama as Obama did him. A book could (and probably should) be written about the negativity of that election.
