Ben Collins, a Green Beret combat officer and businessman, announced his candidacy Tuesday as a Republican lieutenant governor candidate for the 2010 election.
Collins launched a campaign website and filed his candidacy with the Wisconsin Government Accountability Board.
In a statement, Collins said he would focus on ""creating a better business climate"" if elected.
""The lieutenant governor should be working hand-in-hand with the governor's office and the Department of Commerce to develop a blueprint for rebuilding our economy to not only be competitive in the Midwest but throughout the world,"" he said.
State Sen. Spencer Coggs, D-Milwaukee, confirmed in September he will run on the Democratic side. Last month, Lt. Gov. Barbara Lawton announced her exit from the 2010 governor's race and said she will not run for re-election as lieutenant governor.
