Former Missouri Treasurer Sarah Steelman (R) announced she raised just $186,000 in the first quarter of her Senate campaign — a relatively low amount for a candidate whom Republicans view as their frontrunner to take on Sen. Claire McCaskill (D) next year.

Steelman’s haul is only $24,000 more than what her primary opponent, Ed Martin, the underdog in the GOP race, took in during the first three months of this year. Nonetheless, in a statement from her campaign, Steelman said she was “continuing to put together a top campaign organization.”

“The support I’ve received from donors across the state is inspiring and proves Missourians want a U.S. Senator who stands up for families and job creators, not one who represents special interest groups,” Steelman said in a statement about her fundraising. “I am continuing to put together a top campaign organization to ensure I have the resources necessary to be a strong voice for Missouri families in the U.S. Senate.”

Steelman’s campaign released her fundraising numbers Friday evening, just a few hours before the midnight deadline to file her report with the Federal Election Commission.
