Democratic U.S. Rep. Collin Peterson raised nearly $218,000 since the start of the year and has $522,000 banked for his reelection bid.
Two GOP groups – American Future Fund and the National Republican Congressional Committee -- have already spent nearly a quarter million dollars on ads in Peterson's western Minnesota district, which leans conservative.
Peterson's Republican challenger, state Sen. Torrey Westrom, raised roughly $84,000 by the end of 2013. Westrom has yet to post his first quarter 2014 fundraising numbers ahead of Tuesday's filing deadline.
Peterson, the lead Democrat on the House Agriculture Committee, is seeking a 13th term in Congress. Close to 80 percent of his campaign contributions for this election cycle have come from political action committees, most of them with ties to agriculture.
