GREEN BAY, WI (WTAQ) - Wisconsin Republicans are heading to Green Bay for their annual state convention Friday night and Saturday.

Governor Scott Walker said he hoped for a fair and respectable discussion about the party’s endorsement in the U.S. Senate race. That was after reports that candidate Mark Neumann was more aggressive than the others in lining up delegates who will choose him – even by campaigning in counties where delegate commitments were already made.

Walker said the GOP has a, “distinguished slate” of Senate candidates – including former ex-Congressman Neumann, former Governor Tommy Thompson, state Assembly Speaker Jeff Fitzgerald, hedge fund manager Eric Hovde whom Walker called a “successful businessman.”

Walker called for a fair discussion, and he wants delegates to, “put their support behind the candidate who they feel will provide the best contrast to Tammy Baldwin’s liberal record in Congress.”

Walker said all the candidates know the importance of standing together and uniting.

Over 1,300 people will attend the convention. One candidate needs at least 60 percent of the delegates’ support in order to get the party’s endorsement.
