Former state Rep. Geoff Duncan appears to have beat Duluth-based state Sen. David Shafer in the Republican runoff for lieutenant governor Tuesday night by such a slim margin that it is likely headed for a recount.

With 100 percent of the precincts reporting, Duncan narrowly led Shafer by just 1,730 votes.

When the candidates are within 1 percent of each other, the loser can ask for a recount under state law, opening up the possibility that the race could remain unsettled for at least a few days. Results are unofficial pending the counting of any provisional ballots and certification by each county's elections department.

Just before midnight, Duncan tweeted, thanking Shafer for his service and looking ahead toward the general election.

"Congratulations to  on his service to our state and on a very competitive race. He’s a tough as nails opponent and he’s made me a better candidate for the general election. "

While not as heated as the Republican race for governor, the GOP runoff for lieutenant governor wasn’t a friendly contest, either. Duncan had painted Shafer as a government insider and accused the senator of being unethical. Meanwhile, Shafer said Duncan was deceiving voters and he set up a website to discount claims made by his opponent’s campaign.

Shafer declined to comment about the results during an election night party at Madcaps in downtown Duluth.
