The Olympic flap will have no impact on the presidential race, but it is a useful reminder of how careful Romney needs to be. He can’t get away with–let’s just pick a few examples at random–getting the number of states wrong; or referring to the Austrian language; or mispronouncing corpse-man; or saying the private sector is “doing fine;” or promising to bring “inefficiencies” to our health care system; or saying he bowled like was in the “Special Olympics, or something”–well, you get the picture. Romney is not playing on a level field, and the silly press reaction to his London interview should remind him of the fact. He will, in all likelihood, win in November, but in the meantime, he is walking through a minefield with very little margin for error.
