The GOP lost because they ran grandpa against a young, energetic, articulate candidate that promised "change". Grandpa and his outspoken VP runningmate ran the undecideds and moderates to the Dems!
BTW, there aren't enough Conservatives to elect a President. To win, they need to have the ability to pull from the undecideds and moderates. Which means they need to keep thier message focused on the economy and jobs and drop the Draconian social agenda.
The election debate needs to be about the Economy and Jobs. That includes effective policy in budget, re-evaluating most regulations, Foreign Policy and a realistic energy policy for both now and the future. If they stray from that message, they'll get beat.
