MILWAUKEE -- Former Rep. Mark Neumann announced his candidacy for governor Wednesday.

The 55-year-old Neumann joins Milwaukee County Executive Scott Walker and Appleton businessman Mark Todd in the Republican field for next year's race.

In an interview on WTMJ-AM, Neumann said his private sector experience as a businessman are skills needed to lead the state and bring jobs back to Wisconsin. Neumann said Walker has been in the political world most of his career and lacks the private sector experience he can bring to the job as governor.

"I honestly believe when they look at this they'll decide where we are at right now in this particular point in history; they're going to decide that the credentials we bring to this office are the right credentials. I have no motivation to do this job other than I care about what my kids and my grandkids are going to be working a generation from now," Neumann said.

Neumann served in Congress between 1995 and 1999 but has been out of politics since he ran a close race in 1998 trying to unseat Democratic U.S. Sen. Russ Feingold.

He now runs a real estate development firm and is a home builder.

While there will be a Republican primary, Gov. Jim Doyle didn't say Wednesday whether he will run for another term, saying he has a lot of work to do carrying out the recently passed state budget and that he'll worry about another possible run for governor in the future.
