His Kenyan father left not long after Obama was born. He was still an infant. Obama’s mother married Soetero in Hawaii. You are fixated on the Islamic connection. I am more concerned about the communist/socialistic, anti-establishment influence of Ayers, Dohrn, New Party, etc., which are more relevant if Obama becomes the President.
It's all related. being raised with a lot of Islamic influence would make him more susceptible to the communist/socialistic- anti- establishment influence of Ayers, Dohrn, etc. Especially it appears, since his own mother was a ultra lefty.
NO doubt Obama knew all about Ayers before he even met him.
