“[L]et’s just say that not everybody has achieved as much in these last four years as you have.” That was Mitt Romney early in his address to Liberty University graduates on Saturday, the lightest of touches on the heaviest burden President Obama carries into the election season: the president’s utter failure to get the economy growing again at anything resembling the rate that historically attends a recovery after a recession.

It was a good line, deftly delivered, so it was no wonder most media coverage of the speech led with that jab.
