Christian voting

I learn to appreciate Paul more and more. He's got a great post about voting. Some Christians have certain issues that are make or break issues for them (in this case abortion and homosexuality). But Paul and I do not. We can imagine cases where you'd vote for someone you disagreed with on those issues because you thought her/him a better candidate. I acknowledge that, for some people, those are the the most important issues, and that's OK. However, I think in a lot of cases people haven't thought critically about whether they should be make or break issues or not (meta-thought? thinking about thinking...). I think many (most?) Christians approach politics too simplistically.
