How does the Religious "Right" contend with Hypocrisy

Many conservatives are ready and willing to invoke "their" god when it comes to matters of political discourse. Abortion, School Prayer, and vouchers (yes they relate here), bring out the love of god in a conservative faster than you can blink. But, just try mentioning immigration, and social programs that help the needy, and they suddenly develop spiritual amnesia. The God that I know, says to feed the hungry and clothe the naked. The God I know says to treat our neighbors as we would ourselves. Is it not the same God (god)? Why when challenged with what they profess to believe do they suddenly throw up their hands? Is it guilt? Is it shame? I think we all kniow that is not the case. Lastly, the God I know asks that He be served in spirit and in truth...and there is something to be said for His abjorration of lukewarm servants.
