One of the most competitive 2026 House races is heating up, with the leading Democratic challenger to Republican Rep. Juan Ciscomani raising nearly $1 million in the last three months of 2025, NOTUS has learned.
The race for the seat in Arizona’s 6th Congressional District is one of the tightest in the country, with Ciscomani consistently ranking as one of the most vulnerable Republicans in the House. In 2024, he outperformed Trump in the district, winning his race by around three points, compared to Trump’s less than one point.
JoAnna Mendoza raised over $950,000 in the fourth quarter, according to campaign numbers first shared with NOTUS. Mendoza also outraised Ciscomani in the third quarter, $669,362 to $458,703. (At the end of the third quarter, Ciscomani had over twice as much cash on hand as Mendoza, $2,373,585 versus $949,684. It’s unclear how much either candidate has now, and how much Ciscomani raised in the fourth quarter.)
“Even as working families struggle, I’m honored by the support and momentum our campaign has built as we head into 2026,” Mendoza said in a statement. “Southern Arizonans are fed up with Juan Ciscomani’s lies and betrayals, and they’re ready to elect a servant leader who will fight for them in Washington. Failure is not an option — we’re going to win in November.”

Ciscomani is also one of the top recipients of Speaker Mike Johnson’s Grow the Majority PAC.
According to a NOTUS analysis of available campaign data, he received $425,211 from Grow the Majority, making him the fourth Republican incumbent to get money from the PAC. California Reps. Young Kim, David Valadao and Ken Calvert, all of whom face tough reelection challenges after the state’s redistricting, were the only Republican incumbents to receive more money from the PAC than Ciscomani.
Ciscomani’s campaign and his office did not respond to NOTUS’ request for comment. Ben Petersen, a spokesperson for House Republicans’ campaign arm, said in a statement that “Arizona can’t afford lobbyist JoAnna Mendoza’s liberal agenda of making workers and families pay even higher taxes.”
“Mendoza will fall flat because she’s a phony out of touch with Arizonans.”
