Rep. Rodney DavisRodney Lee DavisThe Hill Interview: Missouri Republican has gavel on his radar Is there room for another GOP caucus? Main Street chairman says yes The Hill's Whip List: Where Republicans stand on tax-reform bill MORE (R-Ill.) pulled in more than $600,000 in the last fundraising quarter and has $940,000 left in the bank after an expensive primary, according to his campaign.

The big fundraising haul will help him in his race against former Judge Ann Callis (D). Davis holds one of the most competitive swing districts in the country — President Obama and Mitt Romney essentially tied there in 2012.

Callis, who had a competitive primary of her own, has yet to announce her fundraising figures for the quarter. She had $450,000 in the bank as of the end of February.
