Democratic-Farmer-Labor Rep. Rick Nolan has defeated Republican Stewart Mills in their rematch in Minnesota’s 8th District, the Associated Press projects. Nolan led Mills 50.29 percent to 49.71 percent, with 100 percent of precincts reporting.

The contest was the most expensive House race in the country. Outside groups spent big in the district, which represented one of just three chances Republicans had to knock off a Democratic incumbent this year. Looking to narrow their deficit in the House, this was a must-hold seat for Democrats.  

Minnesota’s 8th District covers the northeastern corner of the state, stretching from the Canada border to outer-ring Twin Cities suburbs in the south. It is home to the Iron Range — the once-prosperous iron ore and taconite mining region just northwest of Duluth.Rolcall
