on election day, if act 18 is not injoined then voters will be faced with the serious threat of losing their right to vote. that was david gersch, the lead attorney for the plaintiff in the pennsylvania voter i.d. law presenting oral arguments before the pennsylvania supreme court this week. the plaintiffs, including the advancement project and the american civil liberties union are seeking to overturn a lower court s judges to deny their injunction and stop the law from taking effect. the final decision over whether or not pennsylvania s voters will be required to show voter i.d. on election day now rests in the hands of the six judges. they are evenly divided, 3-3 between democrats and republicans. a split decision would mean the law stays in effect, which some estimates say could leave 1 million registered pennsylvania voters completely shut out of the election. joining me now from washington,
