My best guess is that his parents were not legally married. He claims he never bothered to confirm it, but I think the true translation of his words is more likely, "I tried to confirm it but couldn't."
Well if he were still married in Kenya, he would be ineligible to marry anyone in any state in the US.
If his parents were not legally married, that should be a poltical plus for him with his ideological base!
That is a given and is public knowledge, his father was still married to his first wife when he married Obama's mother, therefore their marriage would not be valid.
Obama Sr moved to Nairobi, where he took a correspondence course to complete his schooling, studying at night while working as an office clerk by day. He wrote to dozens of US universities. The University of Hawaii replied, offering him a scholarship. Leaving behind his infant son, Roy, and his young wife, Kezia, who was pregnant with their daughter, Auma, he flew to America.Being the university's first African student did not discourage him. He graduated top of his economics class. He married a white student from Kansas, Ann Dunham, and they had a son, who he gave his full name: Barack Hussein Obama.
Obama Sr continued his studies at Harvard, but his marriage soon faltered. When he returned to Nairobi a few years later it was with a different white American woman, Ruth. Together, they had two children. But Obama Sr was still seeing his first wife, Kezia, on the side, and she bore him two more sons. Later, as ethnic rivalries hampered his career as a senior government official - the Obamas are Luo, while the government was largely Kikuyu-dominated - and as he increasingly turned to drink, he had an eighth child by another Kenyan woman.
“My best guess is that his parents were not legally married.”
If that were true, that would make him a real “Bastid”.
