On the Trail: June 5

Obama's campaign strategy of going after rival Mitt Romney's tenure at the venture capital firm Bain Capital has drawn criticisms from Republicans and Democrats alike. Now Chicago is going after the presidential hopeful’s time as governor of Massachusetts. "Romney campaigned for governor on the promises of more jobs, decreased debt and smaller government," Obama senior adviser David Axelrod wrote in a detailed memo last week. "When he left office, however, state debt had increased, the size of government had grown, and over his four years, Massachusetts' record of job creation was among the worst in the nation." A new ad titled “Heard It Before" also goes after Romney's economic record in the Bay State.
