Social issues dividing GOP?

Deep rifts within the Republican party on social issues such as marriage equality, immigration and reproductive rights may make it difficult for the party to unite behind Mitt Romney, despite the efforts of GOP staffers to emphasize health care and the economy, observers say. 

"There's no compelling evidence that the traditional conservative approach to the economy, or foreign policy, or education can't be successful in a national election. But what's absolutely clear is that the party needs to find a way to broaden its demographic base to even be heard on those issues," said Dan Schnur, a former GOP consultant.
