In 1872, Kellogg ran on the Republican ticket and was elected governor. He resigned from the Senate to take office. In the election, John McEnery, a Democrat, ran against Kellogg. The sitting Governor Henry Clay Warmoth, although a Republican, opposed the Republican Party faction that was loyal to President Ulysses S. Grant, who was supporting Kellogg. Warmoth supported McEnery.
Former Confederate Assistant Secretary of War John Archibald Campbell was involved in the controversy surrounding Kellogg. He was a member of the "Committee of One Hundred" that went to Washington to persuade President Grant to end his support of what they called the "Kellogg usurpation". Grant initially refused to meet them but later relented. Campbell stated the case before Grant but was refused.
The results of the election were disputed by the Democrats. The politics of the state was in turmoil for months, as both candidates held inauguration celebrations, certified their local candidate slates and tried to gather political power. Political tensions broke out in violence, including the Colfax Massacre in April 1873. As Governor, Warmoth controlled the State Returning Board, the institution which administered elections. With the election challenged, Warmoth's board named McEnery the winner. A rival board claimed Kellogg to be the victor, although the board had no ballots or returns to count.
