(AP) - Wisconsin voters approved a constitutional amendment in Tuesday’s elections that prohibits foreign nationals from voting in the state. “Voters have delivered an unmistakable message: Wisconsin elections will be decided by U.S. citizens, not far-left activists who would turn the ballot box into a petri dish for extremist policies,” state Republican Party Chair Brian Schimming said in a statement. Republicans across the country have been pushing voters to adopt constitutional amendments that explicitly prohibit non-U.S. citizens from voting. The move was spurred by the District of Columbia and municipalities in California, Maryland and Vermont allowing non-citizens to vote in local elections. The Wisconsin Constitution states that every U.S. citizen who is at least 18 can vote. The amendment revises that language to read that only U.S. citizens can vote in federal, state and local elections held in Wisconsin. The amendment was on the ballot in seven other states besides Wisconsin this cycle, according to Ballotpedia. North Dakota, Alabama, Florida, Colorado, Ohio and Louisiana have already adopted it. Democrats contend the measures could create hurdles for legal voters and lead people to believe that the problem of noncitizens voting is bigger than it really is. Data from states indicates that voting by noncitizens is rare, although Republican officials in Alabama, Georgia, Ohio and Texas have highlighted voter registration reviews that turned up potential noncitizens.
