A court battle over the state of Pennsylvania’s controversial voter identification law is being seen as a proxy in the battle between Republicans and Democrats.  The Pennsylvania Supreme Court has asked a lower court to reconsider its earlier ruling in favor of the law.  Republican legislatures across the country have pushed voter ID laws – ostensibly to prevent voter fraud.  Democrats argue the laws are an attempt to suppress minority voter turnout. Democratic volunteers are canvassing Philadelphia neighborhoods with information on the state’s new voter ID law. The Republican-sponsored law requires voters to have state-approved photo ID to vote. But more than 700,000 voters may not have one.
