MADISON, Wis. -

Jefferson County's current District Attorney, Susan Happ, has won the Democratic nomination for attorney general.

The three-way race for attorney general topped the ticket for Democrats on Tuesday in Wisconsin's statewide primary, with most of the biggest battles — including a competitive race for governor — still to come this fall.

The attorney general's seat is open after incumbent Republican J.B. Van Hollen decided against seeking a third term.

Happ beat out state Rep. Jon Richards of Milwaukee and Dane County District Attorney Ismael Ozanne.

Unofficial results from the primary show that Happ got 54 percent of the votes, Richards got 30 percent and Ozanne got 16 percent.

Happ will face Waukesha County District Attorney Brad Schimel, a Republican, in November.

"(People) want their attorney general to bring us back together. They want their attorney general to protect our rights, the right for women to make their own healthcare decisions, the right to vote," Happ said Tuesday night.

The candidates for attorney general struggled to differentiate themselves in a campaign where they largely agreed on most issues. Richards is the only one of the three without experience as a prosecutor. Happ is the only one who doesn't support making first-time drunken driving offenses a crime, rather than just a traffic citation as it is now.

Ozanne lagged in fundraising, while Richards was the first to get on television with an ad touting his experience. Happ released her first spot a week before the election, showing her riding a motorcycle and emphasizing her experience as a prosecutor.
