This will ultimately be their undoing. Many place their hopes in political institutions rather than God. They are engaged in politics which invariably involves compromise and negotiations. If one's principles trump one's politics, you will be frustrated in success and frustrated by defeat.
If one wants to play the political game, one has to play by political rules. You have to WIN elections to have a place at the table. If you consistently lose and maintain your principles you have nothing and will get nothing out of the political game. You become irrelevant.
Dobson and other evangelical who bolt and cause the GOP to lose will become less not more relevant.
By nominating Giuliani it is you who will break the coalition. You know what nominating an abortion supporter will do and you are advocating it anyway.
Samuel Johnston:
It is apprehended that Jews, Mahometans (Muslims), pagans, etc., may be elected to high offices under the government of the United States. Those who are Mahometans, or any others who are not professors of the Christian religion, can never be elected to the office of President or other high office, [unless] first the people of America lay aside the Christian religion altogether, it may happen. Should this unfortunately take place, the people will choose such men as think as they do themselves.
[Elliots Debates, Vol. IV, pp 198-199, Governor Samuel Johnston, July 30, 1788 at the North Carolina Ratifying Convention]
Very well stated.
