HERMANTOWN, MINN. – When a battle for a congressional seat becomes as taut as the one between Democratic Rep. Rick Nolan and GOP challenger Stewart Mills, campaigns start behaving frantically. Candidates drive hundreds of miles a day, squeezing in a coffee with a veterans group, in between picking up a national surrogate at the airport and dropping into call centers to thank volunteers, with the occasional hug for the random stranger who just picked up a yard sign.
Here in the Eighth Congressional District, whose geography and politics straddle Canadian boundary waters, blue-collar union miners, the artsy funky class of Duluth and the conservative exurbs of North Branch, the fight between Mills and Nolan has become one of the most closely watched House contests not just in the state, but the nation.
The district now ranks second among all U.S. House races for outside cash pouring in, according to the Center for Responsive Politics. A recent Star Tribune analysis showed that independent groups have pumped more than $12 million into ads, mailers and other efforts to influence the outcome.
The nation's top politicos have beaten a path to northern Minnesota, with Vice President Joe Biden praising Nolan's leadership at a rally in Hibbing last week. On Friday, National Republican Congressional Committee Chair Rep. Greg Walden turned up in this dusty industrial suburb of Duluth to thank Mills supporters.
Once a DFL stronghold, the Eighth has morphed into more of a swing district. Voters here bounced longtime Rep. Jim Oberstar in 2010, replacing him with Republican Chip Cravaack. That lasted two years, and in 2012 — a presidential year — voters swung back to the DFL, electing Nolan.
This time, every major national political forecaster is calling the race for the Eighth a tossup. Days ago, national political expert Larry Sabato at the University of Virginia went further, becoming the first to change the race to "lean Republican."
A win for Republicans here would be a blow to Democrats, and strong GOP turnout could affect the races for governor, senator and control of the Minnesota House.
Ask the candidates why the race is among the country's hairline fights, and they deliver starkly different answers. Nolan blames Green Party candidate Ray "Skip" Sandman for siphoning off 4 to 7 percent of the voters who otherwise might support him. Mills says the race isn't that close, according to his own polls. He says he's in a "battle with the couch" to turn out the Republican base.
