CS Lewis wrote this in The Screwtape letters.
Whichever he adopts, your main task will be the same. Let him begin by treating the Patriotism or the Pacifism as a part of his religion. Then let him, under the influence of partisan spirit, come to regard it as the most important part. Then quietly and gradually nurse him on to the stage at which the religion becomes merely part of the Cause, in which Christianity is valued chiefly because of the excellent arguments it can produce in favour of the British war effort or of pacifism. The attitude which you want to guard against is that in which temporal affairs are treated primarily as material for obedience. Once you have made the World an end, and faith a means, you have almost won your man, and it makes very little difference what kind of worldly end he is pursuing. Provided that meetings, pamphlets, policies, movements, causes, and crusades, matter more to him than prayers and sacraments and charity, he is ours and the more religious (on those terms), the more securely ours. I could show you a pretty cageful down here.

Sadly I see a lot of it and with this last election saw many so called Christians throw their faith out the window for a percieved political win (Romney) and I was attacked almost incessantly for standing for my faith over politics.
While I am still a patriot and have not yet given up the fight, politics is not my religion and I find the closer I get to the Lord and the more involved I get in my ministry, the less I care about politics. This world is not my home.
Makes two of us, in spades.
Post Christian America, with its post Christian majority and post Christian government does not make America the same country some of us grew up in. Our government reflects us, who are now broadly too stupid to reverse at least 50 years of Godless neglect.
And by Conservatives!!!!
