According to Federal Election Commission data, Minnesota's Eighth Congressional District race has attracted the most money from outside groups so far.

The contest between Democratic Rep. Rick Nolan and Republican Stewart Mills has already seen nearly $1.4 million in PAC spending, with much of it coming from Nolan supporters, such as the House Majority Fund and the AFSCME union.

In contrast, the race for the Seventh Congressional District seat, which Republican Torrey Westrom hopes to snatch from longtime Democratic Rep. Collin Peterson, has only seen $245,000 in independent expenditures. Interestingly, the last filing documenting outside spending in that race was from eight months ago.

Minnesota's U.S. Senate race, so far, has drawn relatively little interest from independent spenders. According to FEC filings, outside groups have spent about $140,000 to weigh in on the battle between Democratic Sen. Al Franken and Republican Mike McFadden.

The FEC calculations only include expenditures that represent, "spending by individual people, groups, political committees, corporations or unions expressly advocating the election or defeat of clearly identified federal candidates."
