1930 Wyoming state elections

Incumbent Republican Governor Frank Emerson ran for re-election to a second term. After beating back a challenge in the Republican primary from State Treasurer William H. Edelman, he faced State Senator Leslie A. Miller in the general election. As was the case in 1926, Emerson faced a close race, and only narrowly defeated Miller to win re-election. However, Emerson would die shortly after being sworn into his second term, triggering a special election in 1932.

Incumbent Republican Secretary of State Alonzo M. Clark ran for re-election to a second term. After defeating two challengers in the Republican primary—State Representative A. D. Persson and former State Senator H. S. Kirk—he advanced to the general election, where he was opposed by O. O. Davis, the editor of the Green River Star. Clark overwhelmingly defeated Davis to win re-election. Just weeks into Clark's second term, however, Governor Emerson would die, elevating Clark as acting governor—though he continued to serve as Secretary of State.

State Auditor Vincent Carter was elected to Congress in 1928, and Governor Frank Emerson appointed Roscoe Alcorn, the President the Wyoming Press Association and a former State Representative, as Carter's replacement.[5] Alcorn ran for re-election in 1930, and was opposed by accountant C. H. Reimerth in the Republican primary. Alcorn defeated Reimerth in a landslide and advanced to the general election. No Democratic candidate filed to oppose Alcorn, but A. E. Wilde received enough write-in votes to win the party's nomination. Wilde, however, declined the nomination.[6] Accordingly, the Wyoming Democratic Party named June J. Creswell, the former Converse County Treasurer, as its nominee.[7] Alcorn was re-elected over Creswell in a landslide.

Incumbent State Treasurer William H. Edelman opted to challenge Governor Frank Emerson for re-election rather than seeking a second term, creating an open seat. Harry R. Weston, a banker, won the Republican primary over former Cheyenne Mayor Robert N. LaFontaine, and then faced former State Representative Bert Waddell in the general election. Weston defeated Waddell by a wide margin to win his first (and only) term as Treasurer.

Incumbent Republican Superintendent of Public Instruction Katharine A. Morton ran for re-election to a fourth term. She faced Nelle O'Donnell in the Republican primary, which, despite Morton's longtime popularity, was the closest primary in the state. No Democratic candidates originally filed to oppose Morton, but L. C. Tidball, the former state commissioner of education, received enough write-in votes to win the nomination. Tidball declined the spot, however, citing his belief that politics shouldn't be mixed with schools.[11] Accordingly, the state party named Margaret S. "Anna" Preston, the widow of former state Attorney General Douglas Preston, as its nominee.[12] Despite Morton's long history of electoral landslides and the Democratic Party's poor organization in the race, the campaign between Morton and Preston was quite close. Morton ultimately only won re-election by just 1,382 votes, winning her fourth and final term in office.
