America has the politicians it wants, and the fact that you're still here means the situation doesn't upset you all that much.
Buy off the middle voters with pro-liberty social stands, while stealthly pushing through bold economic reform.
Build a new coalition - dumping the zealots, and stealing voters from the Demons who have been afraid to vote GOP for fear of losing 'social' freedoms.
The theocrats aren't going to vote Demon, no matter what. Even if they vote 3rd party, they won't give demons any votes.
And I'll bet that there are LARGE blocks of more or less pro-capitalist Dem voters who would cross lines to vote for the GOP if they ditched these blue noses.
Now might be the time.
When will be a better time?
Would be a good use of political capital. Realign the GOP and make them election proof.
