In a significant development for Democrats, a candidate in a key Arizona district has amassed over $2 million in donations during the first quarter of the year. This impressive fundraising effort has sparked optimism about the party’s prospects for reclaiming the House.
JoAnna Mendoza, a Marine veteran, is challenging Republican Representative Juan Ciscomani in Arizona’s 6th District. She reports raising more than $2.3 million in the first quarter of 2026. The substantial sum, shared exclusively with POLITICO, indicates that the district, which encompasses Tucson’s suburbs and parts of the southeast Arizona desert, could present challenges for Republicans aiming to keep their congressional majority.
“That number shows that we’re not playing around, that we’re serious and that we’re doing the work,” Mendoza remarked in a Thursday interview.
The district is known for its competitiveness this year, with Democrats having won it in recent statewide contests. Democratic Senator Ruben Gallego secured a victory there in 2024, while Democratic Governor Katie Hobbs and Senator Mark Kelly did so in 2022.
House Democrats view the district — which President Donald Trump narrowly carried two years ago, as one of their top targets for flipping. This is according to calculations from The Downballot.
Juan Ciscomani, who previously served as a senior adviser to then-Arizona Governor Doug Ducey and vice chair of the Arizona-Mexico Commission, has been in Congress since 2023. He narrowly won the district in 2022 by fewer than 6,000 votes, marking a historic first as a naturalized citizen from Mexico elected to Congress in Arizona.
Ciscomani’s team did not respond to requests for comment, and his fundraising totals for the first quarter have not been disclosed.
Mendoza’s campaign has not revealed its cash on hand total. At the end of 2025, Mendoza had $1.5 million available, compared to Ciscomani’s $3.1 million.
Mendoza’s fundraising is among the highest reported by a Democratic House challenger this quarter. In a similar vein, Christina Bohannan, who is campaigning to challenge Representative Mariannette Miller-Meeks in Iowa’s 1st District, also reported raising $2 million.
Nationally, the Democratic Congressional Campaign Committee and the National Republican Congressional Committee are closely matched in fundraising. However, a pending Supreme Court decision that may allow parties and their affiliated committees to coordinate directly with campaigns could benefit Republicans.
Democrats are interpreting a series of off-cycle victories as a potential indicator of a favorable shift ahead of the November midterms.
“What we’re seeing right now is an electorate and a donor base that is frustrated with the state of our nation and our country, and they’re doing something about it,” Mendoza commented. “They’re stepping up in whatever way they can.”
