State Rep. Gary Tauchen, R-Bonduel, is likely to face a challenge for his Sixth District Assembly seat in the fall, with two Democratic candidates and a Libertarian declaring their candidacy. William Switalla, a Shawano County supervisor and Wittenberg village president, is hoping have a second go at Tauchen’s seat after an unsuccessful bid two years ago. He will first have to go up against Shawano doctor Richard Sarnwick, who has also declared his candidacy as a Democratic nominee. The primary for that nomination is Aug. 14. The general election is Nov. 6. Shawano resident Mike Hammond, a 30-year dairy farmer who now runs a small greenhouse business, has also declared his candidacy as a Libertarian. The candidates have until June 1 to turn in at least 200 signatures supporting their nominations.
