This Sept. 15, 2013, file photo shows Pennsylvania Gov. Tom Corbett speaking during a news conference in Harrisburg, Pa. Corbett publicly opposes the legalization of same-sex marriage. One after another and in sometimes evocative language, judges appointed by Republican and Democratic presidents are declaring it's too late to turn back on the topic of same-sex marriage. The latest ruling, in Pennsylvania, was followed quickly by word from Republican Corbett that he would not appeal and instead let the decision take effect. Corbett is facing a tough campaign for re-election this year.
