All we need for 2016 is a plausible conservative candidate who hasn't been thoroughly trashed by the MSM...
I suggested a-general-to-be-named-later for 2012, to avoid the damage of years if MSM sniping -- but apparently generals have as much trouble keeping their pants on as any other politician. If the Republicans wanted my advice, I'd suggest beginning to look for someone for 2016 who isn't on anyone's radar screen yet.
The liberal media trash-compactor will immediately work on any Republican who seems the least conservative.
It can't be helped, and is one reason why so few conservatives make it to the top.
Regardless, I'd say we should start with the list of the most conservative governors, senators & congress-critters, and give them all plenty of opportunity to show us their good stuff.
I think, Dems are now so vulnerable on so many issues, it shouldn't be impossible for somebody to take them on successfully.
