The GOP is a party, not a person, so it does not take a position. Candidates take positions, and various Republicans will take various positions. Many Republicans will continue to oppose SSM and to argue that they wish no state had legalized it by any means. There will be Portman-esque Republicans who will agree that SSM should be legal, but that it should have been left to each respective state instead of being settled nationwide by the Supreme Court. And there will be Republicans who will be completely supportive of what the Supreme Court did. Then again, there will be some who will, as much as possible, avoid talking about SSM.
This is the only correct answer, IMO.
