Tuhia he haere tonu mo tenei whitianga - Ko Richardson he kaitono mo te whakaingoatanga Democratic mo te pooti perehitini 2008, engari i heke i te Hanuere 10, 2008 i muri i nga whakaaturanga koretake i roto i nga whakataetae tuatahi me nga whakataetae. Ahakoa tōna roa o te hītori me te whanaungatanga ki te whānau o Clinton, i tautoko a Richardson i a Barack Obama
mo te whakaingoatanga a te Pirimia i te 21 o Poutu-te-rangi, 2008, hei whakakapi mo Hillary Clinton. Ko te kaitohutohu me te hoa o Clinton a James Carville i whakataurite a Richardson ki a Hura Ikariote mo te nekehanga. I whakautu a Richardson i roto i tētahi tuhinga o te "Washington Post", e whakaaro ana ia "he mea tika kia paruru [i a ia] i te kohurutanga o te tuakiri me nga whakapae kore".
