Republican U.S. Rep. John Kline's leading Democratic opponent, former state Rep. Mike Obermueller, raised $81,150 during the first three months of 2014.
With $1.66 million banked for his reelection bid, Kline has an eight-to-one cash advantage over Obermueller, who has roughly $238,000 in cash reserves.
The other Democrats seeking the Second District party nomination, Thomas Craft and Paula Overby, have yet to file their campaign finance reports.
Kline defeated Obermueller, 54 percent to 46 percent, in 2012.
National Democrats had high hopes for Obermueller's 2014 campaign, but their interest and support has flagged in recent months.
The Rothenberg Political Report, a respected political handicapper, has changed its rating on Kline's seat, which covers the Twin Cities' southern suburbs, to "Safe Republican." Until the change, Kline's seat had been listed as "Republican-favored."
The Rothenberg report cited Obermueller's lackluster fundraising as part of their decision to change the rating.
Unless Democratic groups "decide to spend a couple million dollars to pull Obermueller toward the finish line, it doesn't like this seat will be playing in the fall," the Rothernberg report concluded.
