1910 Wyoming gubernatorial election

The 1910 Wyoming gubernatorial election was held on November 8, 1910. Incumbent Republican Governor Bryant B. Brooks declined to seek re-election. The leading Republican candidates to succeed him were initially former U.S. Senator Joseph M. Carey and Attorney General William E. Mullen. However, shortly before the Republican convention, Carey announced he would instead run as an independent candidate. Shortly thereafter, Mullen was formally nominated by the Republican Party. A week later, at the Democratic convention, Carey was named as the Democratic nominee for Governor. In the general election matchup between Carey and Mullen, Carey won a sizable victory, winning every county in the state, a feat that no other Democratic nominee would accomplish until Dave Freudenthal in 2006.
