Illinois Rep. Rodney Davis raised more than $550,000 in the second quarter, according to numbers provided first to CQ Roll Call.
The freshman Republican's three-month haul brought his cash on hand total to $1.3 million as of June 30.
Davis is a top Democratic target in the highly competitive 13th District. He won here in 2012 by just 1,000 votes, while Mitt Romney and President Barack Obama each received 49 percent. Davis faces former Judge Ann Callis, whom the Democratic Congressional Campaign Committee touts as a top recruit .
Callis has yet to release her second-quarter numbers, which cover fundraising from April 1 to June 30 and are due to the Federal Election Commission by July 15. As of March 31, Callis had $514,000 in the bank.
The race is rated Tilts Republican by Rothenberg Political Report/Roll Call.
