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

In the Second Congressional District, Republican U.S. Rep. John Kline has more than $1.3 million stocked away for his re-election campaign after raising $367,000 during the third quarter.

Kline's Republican challenger, David Gerson, raised $2,085 during the quarter and has $2,000 banked for his bid, according to data filed with the Federal Election Commission. Gerson challenged Kline in last year's Republican primary, capturing 15 percent of the vote.

Among the candidates vying for the Democratic nomination, attorney Mike Obermueller of Eagan raised $73,000 during the quarter, which includes the months of July, August and September. He has $119,000 cash on hand.

Obermueller is making a second run at Kline after losing to him by eight percentage points in last year's election. But with roughly a year to go until Election Day 2014, Kline's war chest is 11 times larger than Obermueller's.

The second district covers the suburbs south of the Twin Cities.

The campaign finance reports for Democratic candidates, Thomas Craft and Paula Overby, were not available on the FEC website Tuesday afternoon.

Democratic U.S. Rep. Tim Walz has $238,500 banked for his 2014 re-election bid in southern Minnesota's First Congressional District 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 stockpiled for the race and businessman Aaron Miller of Byron has $54,714 banked. Blue Earth businessman Jim Hagedorn's finance report was not available on the FEC website Tuesday afternoon.

Benson raised $28,158 during the quarter. Miller loaned his campaign $40,000 and collected another $16,127 in donations.

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 not available on the FEC website Tuesday afternoon.

Four of Minnesota's representatives – Democrats Keith Ellison in the Fifth District, Betty McCollum in the Fourth District and Collin Peterson in the Seventh District and Republican Erik Paulsen – do not have announced opponents.

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 in the bank. Peterson has about $227,000 cash-on-hand after raising $83,000 during the quarter.
