Republican congressional campaigns are dipping deep into their war chests as they go into the final stretch before the Aug. 26 primary.

Filings with the Federal Election Commission show that while donations continue to pour in, Republicans in Congressional Districts 1 and 2 are spending more than they are bringing in.

Retired Air Force Col. Martha McSally leads in the three-person CD2 Republican primary, with supporters kicking in $382,000 this reporting period to McSally’s already sizable campaign fund.

About $40,000 came in from political action committees during the five-week reporting period.

The campaign spent $530,000 and had more than $1 million still in the bank at the end of the reporting period.

Small-business owner Shelley Kais raised about $4,000 but spent $6,100 during the same reporting period. She had more than $11,000 still in the bank roughly three weeks before the primary.

Retired Air Force Master Sgt. Chuck Wooten raised about $5,500 and spent $6,500 in the weeks leading up to the primary.

The winner will face Rep. Ron Barber, who is unopposed in the Democratic CD2 primary. He has nearly $1.5 million in cash reserves.

Barber raised $245,000 between July 1 and Aug. 6, including $85,000 from political action committees.

His campaign spent $309,000 during the same period.

The National Republican Congressional Committee has spent nearly $40,000 in survey research against Barber, according to filings with the Federal Election Commission.

Congressional District 1

In the three-way Congressional District 1 Republican primary, Gary Kiehne put another $100,000 of his own money into his campaign.

The Kiehne campaign’s total income for the reporting period was $119,000. He spent $311,000, mostly on advertising, as early voting began.

He had $145,000 left at the end of the reporting period and $400,000 in loans to repay himself.

State House Speaker Andy Tobin raised about $40,000. The Tobin campaign spent $178,000 and had $82,000 left at the end of the reporting period.

State Rep. Adam Kwasman raised about $31,000 for the period and spent more than four times that much as early voting began. 

Kwasman had $8,425 left at the end of the reporting period and $37,000 in personal loans to repay.

An independent expenditure group, the Hometown Freedom Action Network, paid for $70,000 in ads to support Kwasman.

The winner of that race will face incumbent Democrat Ann Kirkpatrick, who has amassed more than $1.3 million for her campaign. 

Congressional District 3

In Congressional District 3, where neither candidate has an opponent in the primary election, fundraising is much slower.

Incumbent Democrat Raúl Grijalva raised $31,000, including donations from unions, FC Tucson owner Greg Caton and Pima County Administrator Chuck Huckelberry. The Grijalva campaign spent nearly the same amount. 

Grijalva has about $109,000 on hand headed into the primary election.

Republican challenger Gabriela Saucedo Mercer had about $4,600 left at the end of the reporting period. She raised $6,900, mostly in in-kind services, and spent $6,200.
