NBC made news way back in June by challenging Mitt Romney on his claim that President Obama has made the economy worse. Now Romney is taking up his dubious claims once again, saying in Iowa that Obama “lost 2 million jobs”—false—and that Romney created 100,000 jobs at Bain Capital, for which there is no evidence. Fact checkers at PolitiFact and The Washington Post concluded that Romney’s “100,000 jobs” boast is at best unsubstantiated, and it’s possible that his layoffs outnumbered his jobs created during his time at Bain.
