In Wisconsin, a proposed constitutional amendment aims to clarify that only U.S. citizens can vote, raising concerns from the League of Women Voters about potential voter suppression. Meanwhile, early voting begins in Minnesota for the presidential election. Election officials from battleground states are countering claims of widespread noncitizen voting, emphasizing the rarity and existing safeguards against such occurrences. In Arizona, a judge ruled that votes can be counted for Proposition 140, which seeks to establish an open primary system, despite ongoing legal challenges. The judge's ruling noted issues with the process of invalidating signatures, which opponents claim reduce the number of valid signatures below the required threshold. A separate Arizona ballot measure, Proposition 131, proposes an all-candidate primary and ranked-choice voting system.
