One of them is accusing the Republicans of voter fraud despite the clear victories in the race. They're attempting to use a mistake (an incompetent one, at that, but still a mistake) by the county clerk of one county in the state supreme court case, as a hammer to claim election fraud:
With 10 of 11 Waukesha County wards still out -- including all of those in Menomonee Falls -- party spokesman Graeme Zielinski said, "We believe the election in this contest has been tampered with by Waukesha County Clerk Kathy Nickolaus.
"She’s sitting on votes. We believe that right now, there are severe irregularities in Waukesha County once again. We believe the very fate of the Wisconsin Senate hangs in the balance and is in the hands of a woman who has already shown extreme incompetence.”
“We believe there’s dirty tricks afoot.”
