FOND DU LAC (WKOW) -- Democrat Jessica King has defeated Republican Sen. Randy Hopper in District 18.
Unofficial results show King with 51 percent of the vote compared with 49 percent for Hopper.
King is the second Democrat to win Tuesday, while three Republicans held on to their seats.
Control of the Senate rests with a race too close to call targeting Sen. Alberta Darling of River Hills.
Two Democratic incumbents face recall next week.
Democrats would have to defeat Darling and win both of those to take majority control.
