Most agree that Gov. Mitt Romney shook up the presidential race in the first of three debates against President Barack Obama in Denver Wednesday night. He focused on the struggles of the unemployed and low-income households and strongly offered an alternative economic vision as a compassionate centrist. Obama appeared to be struggling himself, leaving many of his challenger’s claims unchallenged. Some criticized the president’s performance as too “professorial” and aloof. According to the first CNN/ORC survey after the debate, 67 percent of watchers said Romney won the faceoff, with one in four giving victory to the president. The second debate scheduled for Oct. 10 focuses on foreign policy.
