George Mason University’s History News Network conducted the poll via email in the spring, asking 679 American history professors at a wide variety of different colleges across the nation to give Obama a letter grade on 15 subcategories, plus an overall grade. Of the 203 historians who responded, they gave him an overall B-, with complaints such as:

* The Affordable Care Act (Obamacare) “did not go far enough”

* The prosecution of Bradley Manning

* The failure to close Guantanamo Bay

* Drone strikes against terrorists
