I've called my State Board of Elections to see what precautions are used to ensure ONLY American citizens are voting at our polls. Since the scandal of ACORN assisting illegal aliens in teaching them how to vote, my concerns were forwarded to my State Representatives. I can assure you MY State no longer deals with ACORN since they failed to pass the strict guidelines associated with that State resulting in them not even bothering to show up at our polls.
Please press for exactly what requirements are used for your State and voice any concerns you might have. I found this practice to be welcomed and just as concerning of them as my voice.
