Voters in Oklahoma decided to restrict voting to “only” U.S. citizens, echoing a broader Republican effort to fight non-citizen voting, which is already rare, according to voting integrity experts. The Associated Press called the race for State Question 834, which will amend Section 1 of Article III to change “all citizens of the United States” to “only citizens of the United States” who are eligible to vote. The measure was winning by an 80 percent margin in the state with more than 57 percent of precincts reporting. Seven other states across the U.S. were considering similar measures.
