Every 2012 contender attended college. They all graduated. They went to schools like the University of Pennsylvania, Columbia, Texas A&M, Morehouse, Penn State and Emory.

But decades have passed since these Presidential candidates first stepped onto campus as freshmen. Is it time for an Econ 101 refresher course?

 
America's Econ 101 professors say yes. In their view, the candidates continue to offer ideas and policies that wouldn't pass muster in their classes --   populated by 18 year-old college students.

"There are so many economic 'misstatements' being made," said Jonathan Lanning, a professor at Bryn Mawr who is teaching two introductory economics classes this semester. "And it isn't confined to any one candidate."

Michele Bachmann promised to bring back $2 gas. Tim Pawlenty suggested sustained 5% GDP growth was a realistic target. Rick Perry would balance the budget with lower tax revenues.

No dice, say the professors.
