The 1904 Wyoming gubernatorial election was held on November 8, 1904. Shortly after he began his second term in 1903, Governor
DeForest Richards died in office, elevating Secretary of State
Fenimore Chatterton to the Governorship and triggering a special election in 1904 to fill the balance of Richards's term. Chatterton ran for re-election, but was defeated for renomination at the Republican convention by
Bryant B. Brooks. Former Congressman
John E. Osborne, the former Territorial Governor, was nominated by the Democratic Party. Aided by President
Theodore Roosevelt's landslide victory over Democrat
Alton B. Parker in the
presidential election, Brooks overwhelmingly defeated Osborne.
Party conventions
As the Republican convention began on May 18, 1904, former State Representative
Bryant B. Brooks was seen as having a slight edge over acting Governor
Fenimore Chatterton, with the leading rumor that the
Laramie County delegation held the balance of power and favored Brooks over Chatterton.[1] Ultimately, the contest between Brooks and Chatterton was not close, with Brooks defeating the incumbent Governor on the first ballot with 83 votes to Chatterton's 41.[2]
Meanwhile, as the Democratic convention began on September 7, 1904, several candidates were seen as likely nominees: former Congressman and Territorial Governor
John E. Osborne; former State Senator
William H. Holliday, the
1894 Democratic nominee for Governor;
Robert H. Homer, a former territorial legislator; and W. Dean Hays,[3] with Osborne seen as the frontrunner.[4] After several days of indecision, Osborne—who had been reluctant to run—allowed himself to be nominated and he was approved by acclamation.[5]
