How old is Obama's dad?

Neither one of his parents, nor his stepfather, are still living. His mother, Ann Dunham, died in 1995 of cancer, age 52. His father died in a car crash in Kenya in 1982, age 46.

Obama's stepfather, Lolo Soetoro, died in 1987, age 52.

(Obama has half-brothers and a half-sister by Obama Sr., and a half-sister by Soetoro.)
