Gov. Doug Ducey used his political action committee to contribute $84,500 to Republican candidates in this year’s primary, writing most of those checks to the GOP’s incumbent lawmakers.

The bulk of the contributions from Ducey’s Arizona Leadership Fund, which he created while serving as state treasurer, went to Republican lawmakers seeking reelection. The only contested primaries in which Ducey’s PAC gave contributions are those in which GOP incumbents are facing primary challenges in either reelection bids or campaigns for open seats in the other legislative chamber.

Arizona Leadership fund gave maximum contributions of $5,000 to several lawmakers in contested primaries. Sen. Jeff Dial, whom Ducey recently endorsed, received a maximum contribution in his reelection campaign, where he faces a challenge from Frank Schmuck. Identical checks also went out to Rep. Steve Montenegro and Rep. Warren Petersen, who are running for Senate seats in their districts.

The only non-incumbent to receive a check from Ducey’s PAC was David Cook, who, along with Rep. T.J. Shope, is running uncontested for the House in Legislative District 8. Cook and Shope, who also received $5,000 from the PAC, face a single-shot challenge in the general election from Democrat Carmen Casillas.

Other recipients of maximum contributions from Ducey’s PAC included Reps. Kate Brophy McGee and Frank Pratt, both of whom are seeking Senate seats and are expected to have tough general election matchups in their relatively competitive districts.

Legislative District 18 Reps. Jill Norgaard and Bob Robson each received $5,000 checks. They will face single-shot Democrat Mitzi Epstein in November. Sen. Sylvia Allen, who will face Democrat Nikki Bagley in the general election, also received a maximum contribution from Arizona Leadership Fund.

Sen. Steve Yarbrough received $4,000 from Ducey’s PAC, though he is running unopposed in the primary and is expected to cruise to an easy victory in the general election in his staunchly Republican district. Yarbrough is the overwhelming favorite to be elected Senate president after the November election.

Reps. J.D. Mesnard and Darin Mitchell, who are both running for House speaker, each received $1,500 from the PAC.

Ducey didn’t give any money to non-incumbents running in contested primaries. Political advisor J.P. Twist said that was intentional.

“The governor doesn’t feel like it’s his role at this point in the election to play in a contested primary,” Twist said.

Ducey also spread some PAC money around in a few non-legislative races. His committee contributed $500 to former Phoenix City Councilman Bill Gates, who is running unopposed for the Maricopa County Board of Supervisors; $500 to Scottsdale Mayor Jim Lane, who faces fellow Republican Bob Littlefield in his reelection campaign; $500 to Maricopa County Attorney Bill Montgomery, who is unopposed in his primary; and $1,000 to Maricopa County Sheriff Joe Arpaio, who faces the toughest reelection of his career.

Arizona Leadership Fund also paid for Ducey’s politically related travel, covering the airfare and hotel costs for his trip to the Republican National Convention in Cleveland in July, along with his June visit with Republican nominee Donald Trump in New York.

“We’re being responsible with the taxpayers’ dollars and only using those on things that we feel are appropriate,” said Ducey spokesman Daniel Scarpinato.

Ducey created Arizona Leadership Fund in 2012, but didn’t raise or spend nearly as much that year, or in the 2014 cycle, as he has this year. In 2012, his PAC contributed only $5,100 to other candidates, while he doled out about $31,000 in 2014, the year he was elected governor.

So far in 2014, Arizona Leadership Fund has given out $90,000. The PAC had $45,000 on hand as of the end of the last campaign finance reporting period on August 18. Twist said Ducey plans to be heavily engaged in the general election, where he’s focused on helping the GOP maintain control of the Arizona Senate.

Ducey’s PAC contributions have been far more prolific than his endorsements. The governor has endorsed only 11 candidates in the 2016 primary. The governor has endorsed Brophy McGee, Dial, Gates, Lane, Montenegro, Montgomery, Rep. Heather Carter, Maricopa County Supervisor Steve Chucri, U.S. Sen. John McCain, justice of the peace candidate Cathy Riggs and Gilbert City Councilman Jared Taylor.
