The bitter, gun toting, God fearing Pennsylvanians have voted and Hillary Clinton has won. The Planet Earth — on Earth Day! — has survived.

If we can trust exit polls, the Pennsylvanians did not appreciate the negative campaigning….

The tough tone of the Pennsylvania Democratic campaign tarnished both candidates — more so Hillary Clinton, with 67 percent of voters saying she attacked Barack Obama unfairly.

Yet it looks to have worked: Late deciders favored Clinton by a wide margin, boosting her to an essential victory in the state.

Late Deciders, Women Favor Clinton
