In you "eyes" yes, but there are others who does not share your opinion. Barry was never seen during his Columbia years by anyone, so where was he then!!
You might be destined to eat crow later!!!
They're probably trying to hide his involvement in the pro-Soviet, communist-led "no nukes", disarmament movement. And perhaps his involvement in the Black Liberation movement out of the nearby Union Theological Seminary. The UTS is sandwiched between Riverside Church (where the KGB front, Institute for Policy Studies, based their "no nukes" mass rallies), and Columbia University. Obama, however, may not have 'technically' attended Columbia University, but rather Columbia College, an undergrad part of Columbia University located within the CU campus.
