Obama got regular scholarships from US based sources. The guy went to a posh LA college on scholarship that was paid by US benefactors. He left for Columbia, also on scholarship and help from his White grandparents. He ultimately finished at Harvard Law on scholarships provided via Harvard. The guy is easily one of the smartest, focused and most driven people that I have read about during my lifetime.
Obama benefitted from scholarships that were given out to outstanding students, that practice is common and benefit outstanding students of all races. Obama was the head of the Harvard Review, dummies do not get that position, it is considered too important, only the best have been chosen to lead it, ever.
