MILWAUKEE (AP) -- The Government Accountability Board won't allow a Republican candidate on the ballot in a Senate recall race because he didn't have enough valid signatures.

The Democratic Party of Wisconsin had challenged 39 of Rep. John Nygren's 424 signatures and the GAB found that only 398 were valid. The requirement is 400.

Nygren filed nomination papers to run in the recall election against Democratic Sen. Dave Hansen of Green Bay. The GAB did allow David VanderLeest of Green Bay on the ballot during a hearing Monday.

The two Republican candidates challenging Sen. Jim Holperin of Conover were also allowed on the ballot Monday.

The general election in the Hansen race will be held July 19. The primary in the Holperin race will be July 19, with a general election Aug. 16.
