Among those coveting Harding's seat were former governor Willis (he had been defeated by James M. Cox in 1916) and Colonel William Cooper Procter (head of Procter & Gamble). On December 17, 1919, Harding made a low-key announcement of his presidential candidacy.[71] Leading Republicans disliked Wood and Johnson, both of the progressive faction of the party, and Lowden, who had an independent streak, was deemed little better. Harding was far more acceptable to the "Old Guard" leaders of the party.[72]
Daugherty, who became Harding's campaign manager, was sure none of the other candidates could garner a majority. His strategy was to make Harding an acceptable choice to delegates once the leaders faltered. Daugherty established a "Harding for President" campaign office in Washington, run by his confidant, Jess Smith. Daugherty also managed a network of Harding friends and supporters, including Frank Scobey of Texas, clerk of the Ohio State Senate during Harding's years there.[73] Harding tried to shore up his support through incessant letter-writing. Despite the candidate's work, according to Russell, "without Daugherty's Mephistophelean efforts, Harding would never have stumbled forward to the nomination".
