evidence: With Republican officials around the country like Allen putting a fresh focus on preventing noncitizens from voting — which is already illegal and rare — it’s naturalized Americans like Esternita Watkins who will be most affected by such voter roll purges, voting rights advocates and attorneys say. [...] Allen announced he had put 3,251 voter registrations on track for removal in mid-August as part of a new process that flags anyone on the state voter rolls with a noncitizen identification number. Allen shared the list with the attorney general for "further investigation and possible criminal prosecution," his office said in a release. [...] Allen is among a spate of Republican officials who have sought to crack down on noncitizen voting ahead of the presidential election. Officials in Texas, Virginia and Ohio have recently said they are removing noncitizens from their voter rolls, while House Speaker Mike Johnson, R-La., has championed legislation to require documentary proof of citizenship.
