Andy Biggs picks Sine Kerr as running mate in 1st Arizona election with lieutenant governor

Republican gubernatorial nominee Andy Biggs named Sine Kerr as his running mate Friday, completing the GOP ticket for Arizona’s November general election.

The announcement was made in an exclusive story from The Arizona Republic.

Biggs also released a campaign video introducing Kerr as his running mate.

The daughter of an Army combat veteran and a naturalized U.S. citizen from Mexico, Sine Kerr has lived the American Dream.

Kerr is a former Arizona lawmaker and West Valley dairy farmer who was appointed by the Trump administration as state executive director of the USDA Farm Service Agency in May 2025.

She will campaign alongside Biggs as he runs to unseat Democratic incumbent Gov. Katie Hobbs.

If Biggs wins, Kerr would become Arizona’s first lieutenant governor and help define the office for Arizona voters and shape how future administrations use it.

Why is the lieutenant governor selection significant?

Arizona voters approved Proposition 131 in 2022, establishing the lieutenant governor’s office beginning with the 2026 election. November will be the first time candidates for Arizona governor and lieutenant governor appear together on the general election ballot.

Gubernatorial nominees must select their running mates at least 60 days before the general election. Hobbs has until Sept. 4 to make her selection.

The lieutenant governor will replace the secretary of state as the first person in the line of succession. The lieutenant governor would assume the governorship if the sitting governor dies, resigns, is removed from office or becomes permanently unable to perform the office’s duties.

Beyond that responsibility, the office remains loosely defined, giving the governor broad discretion over the lieutenant governor’s role. The person elected in November will therefore help establish how the office operates in Arizona.

Hobbs has not yet picked a lieutenant governor, but she was turned down by Jimmy McCain, the son of late Sen. John McCain, as a candidate.

Hobbs has said she is open to filling the role with a Republican.
