Early returns show that two U.S. House members -- 2nd District Republican John Kline and 7th District Democrat Collin Peterson -- have healthy campaign accounts as they gear up for the November election.

Kline has more than $1 million banked and with about 42 percent of donations coming from political action committees. Records show that he donated $5,000 to the Republican Party of Minnesota, which is struggling with debt. Kline's own political action committee, Freedom and Security, also donated $5,000 to the party.

His lone Democratic challenger, Northfield City Council member Patrick Ganey, has not yet filed campaign finance documents for the reporting period that covers January through the end of March. The 2nd congressional district covers areas south of the Twin Cities.

Peterson, whose district covers much of western Minnesota, has about $752,530 on hand for his re-election bid against Lee Byberg, a familiar opponent. The Republican Party of Minnesota has endorsed Byberg, who ran against Peterson and lost in the 2010 election by more than 17 percentage. Byberg's campaign had yet to file campaign finance reports as of Wednesday morning.

Considered a conservative Democrat, Peterson has generally won re-election by wide margins. As the ranking Democrat on the U.S. House Agriculture Committee, many of Peterson's first quarter donations came from political action committees with ties to the farming industry.
