Incumbent Sen. Kyrsten Sinema (I-Ariz.) has continued to add to her campaign’s $10 million war chest, but Democratic challenger Rep. Ruben Gallego is catching up, raising $3.1 million over the last three months — compared to the $1.65 million his former party member raised during the same period. The only major Republican candidate, Pinal County Sheriff Mark Lamb, began his campaign in April and has raised $608,000 since.
Sinema has yet to officially announce her candidacy, though internal presentations and her donation pages suggest that Sinema is gearing up to run for reelection as an independent. Sinema left the Democratic Party in December 2022 — saying she “never fit neatly into any party box” — but continues to use ActBlue and Democracy Engine, donation processors that almost exclusively serve Democrats.
New Federal Election Commission filings show that Sinema ended June with $10.8 million, more cash than both of her opponents combined, twice over. Gallego ended the month with $3.8 million and Lamb with $335,000.
Unlike her opponents, Sinema raised hardly any money from small donors. About $9,000 of the $1.85 million she raised came from donors who contributed $200 or less. Meanwhile, more than half of the fundraising done by Gallego and Lamb came from small donors.
OpenSecrets previously reported that Sinema raked in money from big banks, Wall Street and prominent conservative donors during the first three months of 2023. The last three months have been similar, with Sinema getting money from PACs affiliated with Bank of America, Capital One, Morgan Stanley and the U.S. Chamber of Commerce. In total, PACs made up $235,000 of direct contributions to Sinema during the second quarter.
Sinema’s joint fundraising committee, the Sinema Leadership Fund, received an additional $34,000 from PACs, including $12,500 from a PAC affiliated with Fox Corp. Sinema’s campaign committee received about $726,000 from the Sinema Leadership Fund over the last three months, which itself raised $923,000 during the second quarter.
In the first quarter, Sinema received $10,000 from Sen. Lisa Murkowski’s (R-Alaska) Denali Leadership PAC, but she did not report contributions from other campaigns during the last three months, unlike her opponents.
Gallego – who announced his campaign in January 2023 – has continued to receive support from Democrats, receiving over $20,000 through campaign committees and leadership PACs during the past three months. His biggest contributors are Rep. Colin Allred’s (D-Texas) leadership PAC and 2022 Arizona congressional candidate Kelly Cooper’s campaign committee, which each gave Gallego $5,000.
Lamb received $2,000 from Rep. Lauren Boebert’s (R-Colo.) leadership PAC and $250 from the leadership PAC of former Rep. Jason Chaffetz (R-Utah). Lamb is also the only candidate in the race to give to his own campaign, contributing $5,000 in late June.
Despite the lack of an official announcement, Sinema’s campaign committee has spent $842,000 over the last three months. She spent at least $311,000 on advertising and $81,000 on fundraising consulting.
Gallego’s campaign spent $2 million over the same period, with $902,000 going to progressive digital firm Aisle 518 Strategies for digital consulting, ad buys and SMS fundraising. He began April with $2.7 million and ended June with $3.8 million. Lamb spent $272,000, spending almost $100,000 on renting lists, which have information on potential voters and donors.
Lamb is the only Republican running, but rumors have swirled that Kari Lake (R), who unsuccessfully ran for governor of Arizona in 2022, may make a bid for the seat. NBC recently reported that she would be making a decision in the fall
“I’ve looked at the polling, to be honest, and I believe I’m the only one who can win that race,” Lake said last week, according to The Hill.
The most recent poll was sponsored by Gallego and conducted by Public Policy Polling, according to FiveThirtyEight. The April poll projected Gallego winning with 43% of the vote, Lamb with 33% and Sinema in last place with 15%. In a three-way matchup against Lake, the poll predicted that Gallego wins with 42%, Lake captures 35%, and Sinema comes in last with 14%.
A February poll by O.H. Predictive Insights predicted Gallego winning in matchups against Sinema and various Republicans. The poll did not include results about Lamb as he hadn’t announced his campaign yet.
