From the New York Times:
"He barely mentions Columbia, training ground for the elite, where he transferred in his junior year, majoring in political science and international relations and writing his thesis on Soviet nuclear disarmament. He dismisses in one sentence his first community organizing job — work he went on to do in Chicago — though a former supervisor remembers him as 'a star performer.'"

"he [Obama] declined repeated requests to talk about his New York years, release his Columbia transcript or identify even a single fellow student, co-worker, roommate or friend from those years.
'He doesn’t remember the names of a lot of people in his life,' said Ben LaBolt, a campaign spokesman."
Obama’s Account of New York Years Often Differs From What Others Say

Another area of fraud would be if he lied on his application to Harvard Law by stating he had a valid Undergraduate degree from Columbia University. So again, if it’s proven that Obo lied about attending Columbia, then he lied to Harvard Law. Which then means he would have lied on his IL Bar application, etc.
No one writes a thesis as an undergrad -was this his masters thesis?
