First Lady Michelle Obama broke the time honored political rule of leaving politics at the water’s edge, seizing an opportunity to score political points against Mitt Romney while both were traveling outside the United States.

Speaking to a CBS News reporter in London, Michelle leapt at the chance to draw a contrast with the presumptive GOP nominee, who had caused a diplomatic flap by questioning London’s preparedness for hosting the Olympic games.

Romney had said, “It’s hard to know just how well it will turn out . . . There are a few things that were disconcerting.”

Michelle countered with a clear effort to draw a contrast with Romney, saying of the British, “They know what they’re doing.”
