In a perfect world that might actually work. Since we do not live in that world, you might as well forget it. The Republican party has ABANDONED that idea, for the "Let's just be Dem-lite".
As I have said MANY times before, I will vote Libertarian UNLESS there is a candidate put forth by the Republicans I can vote for. I WILL NOT vote for a McCain, Romney, Bush, Christie, etc. If they trot out another one of those types, well, they have decided to FORFEIT the next election. The Republicans will never win again without admitting they need the base they have thrown away, and good luck convincing those same people you are willing to work with them now.
