Mike Cox Exits Michigan Governor's Race, Leaving Perry Johnson as John James' Remaining GOP Challenger

LANSING, Mich. — Former Michigan Attorney General Mike Cox has suspended his campaign for governor, narrowing the Republican primary to a head-to-head contest between U.S. Rep. John James and businessman Perry Johnson.

Cox announced Friday that he was ending his campaign following President Donald Trump's endorsement of James, saying the endorsement significantly changed the dynamics of the race. He also said he intends to support James in the general election.

Cox's departure comes as Perry Johnson has continued to build support among many grassroots Republicans, positioning himself as the remaining outsider in the race. With the Republican field now consolidated, Johnson becomes the sole major challenger to James and will seek to capitalize on voters looking for an alternative to the establishment-backed campaign.

A successful entrepreneur and longtime advocate for government reform, Johnson has argued throughout the campaign that Michigan Republicans—not endorsements or political insiders—should ultimately decide the party's nominee at the ballot box. His campaign has focused on issues including reducing government spending, lowering taxes, supporting law enforcement, and expanding economic opportunity.

Cox, who served two terms as Michigan attorney general and previously sought the governorship in 2010, thanked Michigan voters for allowing him to serve as a Marine, prosecutor and attorney general, describing public service as the most rewarding experience of his career.

Johnson, who narrowly missed qualifying for the 2022 Republican gubernatorial primary after thousands of petition signatures submitted by multiple campaigns were ruled invalid, has since rebuilt a statewide political organization and returned to the campaign trail with renewed support from many Republican activists.

With absentee voting underway and the Republican primary drawing closer, the race now becomes a direct contest between James, backed by President Trump's endorsement, and Johnson, who is betting that a strong grassroots organization and outsider message can resonate with Republican voters across Michigan.
