Theresa Greenfield, who launched her campaign to unseat Ernst in June, said she raised more than $1.1 million in the year’s third quarter, compared with reports that Ernst raised just under $1 million in the same span.

The Democrat's campaign, which is refusing donations from corporate PACs, said its average online donation for the quarter was less than $16 and that 92 percent of all contributions received were for $100 or less. Donations to the campaign have come from all of Iowa’s 99 counties.

“It’s clear that the momentum and energy is on our side to flip this Senate seat, and I’m so proud of what our grassroots campaign has already been able to accomplish to lay the groundwork to win this race next year,” said Greenfield.

“After years of watching Senator Ernst answer to Mitch McConnell Addison (Mitch) Mitchell McConnellDemocratic senator to party: 'A little message discipline wouldn't kill us' House to vote on resolution affirming peaceful transition of power Republican lawyers brush off Trump's election comments MORE and the special interests in Washington, Iowans are ready for new leadership and they’re saying ‘no more’ to Senator Ernst. I’m humbled to have the support of so many hardworking Iowans as we work to hold Senator Ernst accountable and give Iowa families the representation they deserve.”

Ernst's campaign said in a statement to The Hill it raised about $1 million in the third quarter and has nearly $4 million cash on hand.

“Iowans are energized behind Joni Ernst and her ability to deliver for the state from securing a strong win on the RFS [renewable fuel standard] to obtaining the long-awaited resources needed for the Cedar Rapids flood project,” said campaign manager Sam Pritchard.

“Joni continues to crisscross the state and ensures Iowans have a voice in Washington, holding 33 town halls just this year. Momentum continues to build as Iowans know they have an effective voice in Joni Ernst who fights tirelessly to Make ‘em Squeal in Washington in order to deliver for Iowans.”

Greenfield first raised eyebrows among Iowa Democrats after she ran for the state’s 3rd District in 2018 but dropped out after she found out that her campaign manager falsified several signatures on petitions qualifying her for the ballot.
