State Rep. Brett Davis, R-Oregon, filed for a possible run for lieutenant governor in the 2010 race Thursday.
Davis said his campaign will focus primarily on the economy and job creation.
The most recent candidate to enter the race, Davis filed paperwork Thursday that allows him to begin gathering resources for a campaign. He said he will spend the coming months traveling around the state to discuss his ideas with Wisconsin citizens.
Davis has not yet confirmed his candidacy.
""I expect to make a final decision on a campaign later this year,"" he said in a statement.
Other candidates from both sides of the aisle are also vying for the position. Superior Mayor Dave Ross, a Republican, filed to run July 3. Milwaukee Ald. Tony Zielinksi, a Democrat, announced his candidacy Aug. 25.
Lt. Gov. Barbara Lawton will vacate the seat in 2010. She announced her candidacy for governor in August.
