WisPolitics.com reports that a Democratic official in Waukesha county vouches for her Republican colleague that an honest mistake led to 14,000 votes not being counted:

Ramona Kitzinger, the Democratic member of the county board of canvass, defended the process. She agreed with Nickolaus that the board "went over everything and made sure that all the numbers jived up, and they did." "I'm the Democratic vice chair of Waukesha County, so I'm not going to stand here and tell you something that's not true," Kitzinger said.
