MADISON, Wis. (AP) _ U.S. Sen. Ron Johnson and the Republican Party of Wisconsin are calling on Republican candidates for Senate to sign a unity pledge.
The proposal put forward Wednesday calls for the loser of the August primary to agree to support the winner. Whoever signs it will be given the names of likely delegates to the state convention who will be voting in May on who will get the party's official endorsement.
State Sen. Leah Vukmir, of Brookfield, is running against Delafield businessman and political newcomer Kevin Nicholson in the GOP primary. The winner will face Democratic Sen. Tammy Baldwin.
Vukmir is well-known among Republicans, having been in the Legislature since 2003. Nicholson's campaign is backed by former President Donald Trump adviser Steve Bannon.
Vukmir and Nicholson say they will both sign a proposed unity pledge.
