Iowa Democrat Sarah Trone Garriott Outraises GOP Rep. Zach Nunn in Blockbuster Fundraising Quarter

Democratic challengers in key U.S. House races posted massive fundraising numbers in the second quarter, closing the GOP's cash advantage in battlegrounds across the country — including right here in Iowa. In the state's 3rd Congressional District, Democratic state Sen. Sarah Trone Garriott raised $2.2 million during this period, more than doubling the $968,000 raised by incumbent Republican Rep. Zach Nunn.

That disparity is part of a broader national trend. According to a POLITICO review of Federal Election Commission filings, seven of the 10 best-fundraising House candidates in competitive districts were Democratic challengers, and all seven outraised the GOP incumbents they are facing. In Pennsylvania's 8th District, Scranton Mayor Paige Cognetti raised just over $2 million, while first-term GOP Rep. Rob Bresnahan raised a little more than $1 million. Both Cognetti and Trone Garriott also vaulted over their GOP opponents in cash on hand.

Democrats Dominate Top Fundraising Hauls

Overall, nine of the top 10 fundraising candidates in battleground House races were Democrats, and 30 of the top 50, according to POLITICO. The strong candidate fundraising signals Democratic momentum as they push to flip the House in November, seizing on voter concerns about the economy after President Donald Trump's return to the White House. National polling indicates Democrats have a strong chance at taking control.

Seventeen Democrats challenging incumbents or running in competitive open seats raised at least $1 million in the second quarter, compared to only four Republicans. And at the other end of the spectrum, nine of the 10 lowest fundraising totals in battleground districts were posted by Republican incumbents or challengers.

GOP Still Holds Cash Edge at Committee Level

Despite the Democratic surge in individual races, Republicans maintain a substantial overall fundraising advantage at the committee level — an edge that could prove crucial this cycle due to a recent Supreme Court decision loosening campaign finance restrictions. The National Republican Congressional Committee has outpaced the Democratic Congressional Campaign Committee and held a roughly $9 million cash-on-hand advantage at the end of May. The Republican National Committee also has a massive lead, with $125 million in the bank compared to the Democratic National Committee's debt of $18.3 million against just $14.8 million in cash.

On the super PAC side, Congressional Leadership Fund, aligned with Speaker Mike Johnson, has just under $142 million in the bank. House Majority PAC, aligned with Minority Leader Hakeem Jeffries, has $66.7 million.

What This Means for Iowa's 3rd District

For Iowa voters, the fundraising battle in the 3rd District underscores the high stakes of this election. Trone Garriott's $2.2 million haul gives her a significant financial boost to challenge Nunn, a first-term Republican who won a competitive race in 2024. Nunn's campaign still has resources, but the gap in fundraising momentum is notable.

Political analysts say the 3rd District, which includes Des Moines and surrounding suburbs, remains a top target for Democrats. The district leans slightly Republican but has been competitive in recent cycles. Voter concerns about the economy, inflation, and government spending are expected to drive turnout on both sides.

GOP Incumbents Still Raising Strong Totals

Republicans are not without resources. Thirteen vulnerable GOP incumbents raised at least $1 million in the second quarter, while only eight incumbent Democrats in targeted districts raised that much. Many GOP incumbents built up cash advantages early in the cycle and continue to haul in strong totals.

However, some Republicans lagged badly. Rep. Cory Mills of Florida had the lowest haul of any incumbent battleground member, raising less than $60,000. Mills, who faces a House ethics investigation, was even outraised by his GOP primary challenger, Ryan Elijah, who brought in just over $300,000. Florida holds its primary on Aug. 18.

Bottom Line for Iowa Voters

The fundraising numbers show that the battle for control of the House is intensifying, with Iowa's 3rd District at the center of the fight. Trone Garriott's strong quarter gives Democrats hope they can flip the seat, but Nunn's incumbency and the GOP's overall financial edge mean the race is far from decided. Voters can expect a barrage of ads and outreach in the coming months as both sides pour money into the district.

For Iowans, the key question remains: Will the Democratic fundraising momentum translate into votes in November, or will Republican organizational strength and voter turnout prevail? The answer will shape not just Iowa's representation but the balance of power in Washington.
