Arizona Republican Gov. Doug Ducey squashed Republicans’ hopes he would launch a Senate campaign to challenge Democrat incumbent Mark Kelly.

In a letter to donors, the term-limited governor said he plans to focus on helping other Republicans running for office.

The Washington Examiner reports:

“If you’re going to run for public office, you have to really want the job,” he wrote in a letter to donors. “Right now I have the job I want, and my intention is to close my years of service to Arizona with a very productive final legislative session AND to help elect Republican governors across the country in my role as chairman of the Republican Governors Association.”

It isn’t immediately clear which candidates will benefit from the governor’s decision. Still, his refusal to enter likely consolidates the race to two candidates: Attorney General Mark Brnovich and Thiel Foundation President Blake Masters. Ducey lauded the “strong field of candidates in Arizona” and vowed he “will be actively supporting our nominee.”

National Republicans led by Senate Minority Leader Mitch McConnell sought to recruit Ducey for the race, hoping his high profile and fundraising abilities could help them edge out incumbent Democratic Sen. Mark Kelly.

However, despite Ducey’s popularity he likely still would have faced an uphill battle to win over the seat after becoming the subject of former President Trump’s wrath for supporting Biden’s 2020 victory.

“MAGA will never accept RINO Governor Doug Ducey of Arizona running for the U.S. Senate — So save your time, money, and energy, Mitch,” Trump wrote in a Feb. 14 tweemail.

The Arizona race is expected to be one of the most competitive in the country.
