Representing two potential swing districts, U.S. Reps. John Kline and Tim Walz have healthy fundraising leads over their opponents.

In the Second Congressional District, Kline, a Republican, has more than $1.3 million socked away for his campaign, after raising $367,000 during the third quarter, according to Federal Election Commission reports.

GOP challenger David Gerson raised $2,085 during the quarter and has $2,000 cash on hand. He challenged Kline in last year’s primary and lost.

DFLer Mike Obermuller, of Eagan, raised $73,000 last quarter in his bid to unseat Kline. He has $119,000 cash on hand. Obermuller, an attorney, is making a second attempt, after losing to Kline by 8 percentage points last year.

The campaign finance reports for other Democratic candidates, Thomas Craft and Paula Overby, were not available Tuesday afternoon.

In the First Congressional District, Walz has banked $238,500 for his 2014 re-election bid, after raising $176,648 during the third quarter.

Among the three Republicans seeking to oust Walz, state Rep. Mike Benson of Rochester has $14,707 on hand, while businessman Aaron Miller of Byron has $54,714. Blue Earth businessman Jim Hagedorn’s finance report was not available.

In the state’s Eight Congressional District, Republican challenger Stewart Mills raised almost $244,000 during the quarter, with Mills and his wife contributing about $10,000 of that total, his campaign reported. Incumbent Democrat Rick Nolan’s campaign finance reports were unavailable.

Four members of Minnesota’s congressional delegation have drawn no opponents: Democrats Keith Ellison in the Fifth District, Betty McCollum in the Fourth District, Collin Peterson in the Seventh District and Republican Erik Paulsen in the Third.

Paulsen raised more than $376,000 and has more than $1.5 million in the bank. Ellison raised $309,000 and has $186,248 stockpiled. McCollum collected $99,219 and has $89,076 on hand. Peterson has about $227,000, after raising $83,000 during the quarter.
