Pennsylvania’s state Supreme Court justices on Thursday aggressively questioned whether a politically charged law requiring photo identification from each voter should take effect for the Nov. 6 presidential election and whether it guarantees the right to vote. With the election just 54 days away, the justices did not say when they will decide, although lawyers in the case expected them to rule before the end of September. The high court appeal follows a lower court’s refusal last month to halt the law from taking effect. The law , championed by Republicans over the objections of Democrats , is now part of the heated election-year political rhetoric in the presidential swing state and has inspired protests, warnings of Election Day chaos and voter education drives.
