I'm not sure if this is a serious question, or one that is dripping with sarcasm. I'm going to take it on face value, because there's no question that the Republican Party has done a great job of courting the evangelical vote. The message sent out by conservative Christian groups (sometimes referred to as the religious right) is that a good Christian will vote Republican. That's an unfortunate message.

The truth is that the primary allegiance of a Christian, regardless of his or her party affiliation, is to God. With this in mind, our relationship to our culture--including the political process and its parties--should be as foreign citizens, or "resident aliens." In this way we are like Abraham, who was called by God to leave his home and go to another country that God would give him as his inheritance. "He went without knowing where he was going. And even when he reached the land God had promised him, he lived there by faith--for he was like a foreigner, living in tents" (Hebrews 11:8-9).

This doesn't mean that we can't be productive and influential in the culture. Jesus told us to be "salt and light." But we have to always remember that our true citizenship is in heaven (Philippians 3:20). I like what Gregory Boyd writes in his book, "Myth of a Christian Nation"--

"Whatever opinions we have about how to solve society's problems, we are to remember always that we cannot serve two masters (Luke 16:13). Our allegiance, therefore, can never be to any version of the kingdom-of-the-world, however much better we may think it is other than other versions of the kingdom-of-the-world. Our allegiance is to our heavenly Father, whose country we belong to and into whose family we've been adopted."

So it's fine to vote Republican, if that's your conviction. And it's fine to vote Democratic. Just don't lose sight of your true allegiance.
