I don't think you can go back ever. You can only progress forward in time and cause change to something more like you want. But you will never ever get something exactly like it was when it started.
Try that in raising a child, making changes in a marriage or friendship. Are you going to continually rage against a child, marriage partner or friend because they have altered from what they were at the beginning?
This is the whole problem I see with the Libertarians - they live their lives trying to go backward to their own preceived ideal. It does not matter to them that voters have evolved the country into something else or why. They will have NOTHING but what was at the beginning.
If they can't have it - they will spend their lives destroying the imperfect conservative efforts of other lesser minds (in their opinion). Thereby, they further the ultra liberal agenda because they keep the new day conservatives tied up fighting with them and unable then to fight the liberal advance. This is allowing the voters to again choose liberalism instead of conservatism and moving the country further from where they want it.
Yet they can never understand. They just think the new day conservatives are following with blind loyalty.
