He would be 71 in 2016. I don't see him surviving a primary, but if a conservative wins the nomination and is looking for someone to help with foreign policy, he could be a possibility. Also would provide a small boost in Pennsylvania.
That being said, white male/white male in 2016 isn't a good idea for the GOP.
While some in the media would criticize it, a white male/white male ticket won't be a big problem IMO. It could help balance geography (Midwest, South, Northeast). (ex: Pence/Thune, Christie/Walker, Bush/Walker). Ridge would be on the ticket unless the presidential nominee may need help in foreign policy.
