Other than "Render unto Caesar" where does he endorse or oppose ANY political view? That's not what Jesus was about.
Paul, who had contact with the other Apostles who spoke with Christ personally and so would have had a pretty good idea of what he taught, seems to think Capital Punishment is OK (Romans 13:4.)
Admittedly, most of the early Christians disagreed with him. I can understand why. They were also absolute total pacifists. I do disagree with that viewpoint Biblically, but for a small group of people who were completely devoted and undergoing persecution, the viewpoint makes a lot of sense in that context. Most of you guys don't have a problem with war, or with the destruction of most fetuses, or self-defense, all of which the early Christians did not believe in, and yet you continually harp on capital punishment and say "Jesus would never have supported that."
Of course, modern politics are fundamentally different from 1st century ones anyways, where there was an Emperor and no "Voting" but that's a completely different topic.
