State constitution does not explicitly prohibit non-citizens from voting. //end headline wrapper ?> Rep. Jim Steineke and Sen. Roger Roth. The Wisconsin Constitution guarantees that every U.S. citizen 18 and over is a qualified elector, however nowhere does it specifically state that only U.S. citizens are qualified to vote in state or local elections. That is a problem that needs to be addressed, according to Sen. Roger Roth (R-Appleton) and Assembly Majority Leader Jim Steineke (R-Kaukauna), who are currently circulating a resolution seeking to amend the state constitution so it “provides clarity that a qualified elector is only a U.S. citizen for the purpose of all elections and ballot measures in Wisconsin.”
