Corey Stapleton (born September 17, 1967) is an American politician and musician who served as the Secretary of State of Montana from 2017 to 2021.

[2] After losing the House race, Stapleton announced in 2021 his intention to pursue a career as a country singer.

[3] After expressing interest in a candidacy for president of the United States in the 2024 election,[4] Stapleton became the first Republican office-holder to announce their run; he withdrew in October 2023 before the primaries.

Nominated by the Secretary of the Navy, he attended the Naval Academy Preparatory School in Newport, Rhode Island.

[20][21] Stapleton ran for Governor of Montana with former state senator Bob Keenan as running mate in 2012.

[25][26] In early 2013, he decided to run for the U.S. Senate and challenge longtime Democratic incumbent Max Baucus.

[33] In July 2017, Stapleton said that there had been 360 cases of voter fraud in Montana in the 2017 special congressional election.

[36] In October 2018, Stapleton came under scrutiny after it was revealed that a Voter Guide written, published, and mailed by the Montana Secretary of State office had failed to distinguish what changes proposed ballot initiatives would make to existing laws through underlining additions and striking deletions, instead printing the new laws without these distinguishing marks.

Stapleton's office awarded the $265,000 contract to print and mail the corrections to all Montana voters to Ultra Graphics, a firm run by former state Republican Party Executive Director Jake Eaton.

[39] A city attorney refused to file charges, referring to the expiration of a one year statute of limitations, although an AP investigation alleged further potential violations occurring after the period of the audit.
