Ko Thomas C. Platt, te "tumuaki" o te New York State Republican Party, kaore i pai ki a Theodore Roosevelt, te kawana rongonui o New York, ahakoa he hoa Republican ia. Ko nga mahi a Roosevelt ki te whakarereke i nga mahi torangapu o New York - tae atu ki nga mahi torangapu a te Republican - i arahina a Platt me etahi atu rangatira o te Republican ki te akiaki i te Perehitini McKinley ki te whakaae ki a Roosevelt hei kaitono perehitini hou, na reira ka whakakii i te waahi i mahue i te wa i mate ai te Perehitini Tuarua a Garret Hobart i te 1899. Ma te kowhiri i a Roosevelt hei perehitini tuarua, ka nekehia atu e Platt a Roosevelt mai i nga mahi torangapu o te kawanatanga o New York. Ahakoa i whakaroa a Roosevelt ki te whakaae ki te whakaingoatanga mo te perehitini tuarua, i whakaarohia e ia he tari iti noa iho, kaore hoki he mana, ko tana rongonui nui i waenga i te nuinga o nga mema o te Republican i arahi a McKinley ki te whiriwhiri ia ia hei hoa whakahaere hou. I te kore e tūmanakohia, ka eke a Roosevelt ki te perehitini i te Mahuru o te tau 1901, i te wā i patua ai a McKinley
