I karangatia ia ki te whakatuunga a te Perehitini Republican a George W. Bush i te tau 2001. I te marama o Hepetema 2007, i kii ia i tana tautoko mo te kaitono perehitini Republican a Rudy Giuliani. I mahi a Duvall i te hui ā-motu o te GOP i te tau 2008
ā, e ai ki tētahi tuhipānui o MSNBC i te 29 o Akuhata 2008, ko Duvall te kaikorero i te nuinga o ngā ataata mō te huihuinga. I te marama o Hepetema 2008, i puta ia i runga i te atamira i te huihuinga a John McCain me Sarah Palin i New Mexico.
