MADISON, Wis. (AP) — A southeastern Wisconsin prosecutor has officially joined the race for attorney general. Jefferson County District Attorney Susan Happ announced Wednesday she'll run for the office. Happ said in a statement she's running because she the state needs a leader who will put Wisconsin families ahead of partisan politics. She didn't list any goals for the office, however. Happ's announcement wasn't unexpected; she filed paperwork with state election officials in late January signaling she had formed an attorney general campaign committee. Happ will face a three-way Democratic primary with Dane County District Attorney Ismael Ozanne and Rep. Jon Richards of Milwaukee. Waukesha District Attorney Brad Schimel is the only Republican in the race. Incumbent Republican Attorney General J.B. Van Hollen announced last year he won't seek re-election.
