Democratic Rep. Rick Nolan won a narrow victory again over Republican Stewart Mills in the battle for Minnesota's northeastern congressional district, an election that was among the state's closest U.S. House races.
As of early Wednesday, Nolan led by a little more than 2,000 votes.
Nolan was running for his third consecutive term in the House, though he also served in Congress in the 1970s. He faced Mills, a member of the family that built the Mills Fleet Farm empire, who narrowly lost the same race two years ago.
Nationally, both Republicans and Democrats saw the sprawling Eighth Congressional District, which spreads from the northern Twin Cities exurbs to the Canadian border, as a toss up. So they threw more than $17 million in mostly negative advertising on TV and radio to try and sway about 650,000 voters.
It was the country's most expensive U.S. House race.
Two years ago, Nolan won by fewer than 4,000 votes. This year, he faced stiff headwinds because of Republican presidential nominee Donald Trump, whose fierce stands against trade agreements galvanized working class voters and helped Mills, who openly supported Trump.
"I am cautiously optimistic and more [cautious] than optimistic because I understand exactly how competitive it is, and it all depends on who shows up to vote," Mills said. "I am confident that I won on the issues."
Mills and his family recently sold off their business to a private firm, and he subsequently plunged almost $2 million of his own money into the race.
