The State House was ground zero in the duel before the Barack Obama and Mitt Romney yesterday, with each camp taking to the storied front steps to critique and tweak each other. To hear Team Obama tell it, Romney was a dismal failure during his four years as governor; to listen to the pre-buttal Team Romney cobbled together in anticipation, Romney was a job-creating wonder compared to Jimmy Carter-esque incumbent president. The actual truth of the matter won’t please partisans on either side. Not if they are in search of simplicity, anyway.
