Update: New information discovered. Obama did register for the selective service in September 1980. Obama tells This Week that he gradudated in 1979. Presumably, that's May or June of 1979, though I suppose it could be December 1979. Occidental claims in this LA Times story that Obama is an alumnus from 1979-1981.
What the LA Times report also tells us is,
In his 1995 autobiography, “Dreams From My Father,” Obama recounted how he was accepted into “several respectable” colleges but chose Occidental “mainly because I’d met a girl from Brentwood while she was vacationing in Hawaii.”If you like Obama this says very little. He's still the guy running for President that has received a massive amount of support from frequent voters and new voters. Lay off him.
If you have questions about Obama, this says what you think you know about his background isn't the same way he talks about it today.
