The AP has this report, on a radio campaign linking illegal immigration and voter identification requirements. The ad, from a group called North Carolina Conservatives United, reportedly states: “Now we need to pass a law that prevents illegal immigrants from getting a driver’s license and requires a photo ID to vote, because a nation of immigrants must also be a nation of laws.” In related news, the Rocky Mountain News has this report on a Colorado bill that would reportedly require proof of citizenship to register and ID to vote.
