I whanau a Obama i Honolulu, Hawaii. I muri i tana tohu i te Whare Wananga o Columbia i te 1983, i mahi ia hei kaiwhakahaere hapori i Chicago. I te 1988, i uru ia ki te Kura Ture o Harvard, ko ia te perehitini pango tuatahi o te Harvard Law Review. I muri i tana tohu, ka noho ia hei roia mo nga tika tangata me te maatauranga, e whakaako ana i te ture ture ture i te Whare Wananga o Chicago Law School mai i te 1992 ki te 2004. I tohu ia i te rohe 13 mo nga wa e toru i roto i te Illinois Senate mai i te 1997 tae noa ki te 2004 i te wa i rere ai ia mo te Senate o te US. I riro ia i te aro o te motu i te 2004 me tana wikitoria tuatahi o Maehe, tana korero nui mo te Democratic National Convention, me tana whenua i te marama o Noema ki te pooti Senate. I te tau 2008, i tohua ia mo te perehitini kotahi tau i muri i tana pakanga me te tiimata i te pakanga tata ki a Clinton. I pootihia ia mo te Republican John McCain ka whakatuwherahia i te 20 o Hanuere 2009.
