Wasn’t Obama at Occidental College during September 4, 1980? Why wouldn’t he register for SSS in Los Angeles?
Perhaps he registered in Hawaii early before going to Occidental- hence- “effective date” ?
I don’t know- but tracking down what’s his name, Daniel Amon is worthwhile.
After high school, Obama studied at Occidental College in Los Angeles for two years. He then transferred to Columbia University in New York, graduating in 1983 with a degree in political science.
It appears he was going to Occidental in LA in 1980, but maybe he was on one of those needed vacations in Hawaii to see grandma at the time he registered for the Selective Service.
