The law passed the GOP-controlled legislature last spring, and was promptly signed into law by Gov. Corbett, a Republican. Since then, it's been the subject of a long - and, at times, nasty - legal fight, with the ACLU and other attorneys for plaintiffs in the case arguing that it will disenfranchise voters, particularly the young, the poor and the elderly. They have also argued that the free ID cards the state was offering through PennDot were laden with bureaucratic landmines, and required voters to produce official documents that many could not obtain.
