"Obama is from Hawaii?"
Yes. From a magazine article:
"Obama was actually born in Hawaii. His father, also named Barack Obama, was a foreign student there. His mother, Ann, was white, and only eighteen when she married his father. She and her parents, originally from Kansas, had moved to Honolulu. When her husband left for Harvard, she and their toddler stayed behind—there was no money in his scholarship for them to go East—and the father ultimately returned alone to Kenya, where he worked as a government economist. Barack’s mother’s second marriage, to an Indonesian oil manager, occasioned a move to Jakarta, when Barack was six. He lived there for four years, and in his book he writes about his time in Indonesia as simultaneously lush and a harrowing exposure to tropical poverty—more harrowing, perhaps, for his mother than for the little boy who barely remembered any other life. Then Barack returned to Hawaii, where he was brought up largely by his grandparents. The family lived in a small apartment—Barack’s grandfather was a furniture salesman and, later, an unsuccessful insurance agent; his grandmother worked in a bank—but Barack managed to get into Punahou School, Hawaii’s top prep academy. His mother always said that he got his brains from his father, and he was raised on tales of his father’s brilliance. The great man wrote to them regularly, but, though he travelled around the world on official business for Kenya, he visited only once, when Barack was ten."
