A second Republican senator has inched toward an embrace of gay marriage. Sen. Lisa Murkowski (R-Alaska) told a local paper Wednesday that her views on the issue were "evolving."

"I've got two young sons who, when I ask them and their friends how they feel about gay marriage, kinda give me one of those looks like, 'Gosh mom, why are you even asking that question?'" she told the Alaska Star. "The term 'evolving view' has been perhaps overused, but I think it is an appropriate term for me to use."
