Well my initial headline was wrong. Usually when 87% of the votes are in, and the results were the way they looked, you can call it.
Kevin Dahle does surprisingly well. At this time, it's 50% to 46%. More than 50 votes apart.
Update: I'd call it a win for Ray Cox when there were 87% in. Now the results have turned around - Kevin Dahle wins.
Independence VANCE NORGAARD 257 3.18
Republican RAY COX 4065 50.37
Democratic-Farmer-Labor KEVIN DAHLE 3741 46.35
Write-In WRITE-IN** 8 0.10
Ray Cox did return my phone call (he left a voice mail at 5:30 PM) and said basically what he'd told "gPRT".
