A potentially major legal battle is brewing in Pennsylvania as the incumbent Democratic senator, Bob Casey, has yet to concede defeat to the Republican candidate, Dave McCormick, and an automatic recount is set to occur. Republicans have already filed lawsuits to block the counting of certain votes, as some commissioners have agreed to count some contested ballots despite court orders. 

On Thursday, the Pennsylvania Republican Party filed a lawsuit with the state’s supreme court over the decision by several counties to count ballots without dates on them, despite an order from the state Supreme Court.
