MADISON, Wis. (AP) -- The Latest on Wisconsin's primary election (all times local):
8:25 p.m.
Wisconsin Republican Gov. Scott Walker has dispensed with a nominal GOP challenger as he awaits the winner in a crowded Democratic primary.
Walker is seeking a third term in office, after he failed in his 2016 presidential run. Eight Democrats were seeking to challenge him in November.
Walker handily defeated his token opposition, Robert Meyer, who was not actively campaigning. Walker has amassed nearly $5 million and already run more than a dozen television ads as he positions himself for the fall election.
Democrats are optimistic that this year presents their best chance ever to take down Walker. They've scored unexpected election victories in other races this year and polls generally show Republicans to be vulnerable.
In 2012, Walker became the first governor to ever defeat a recall election.
