When we start talking about extra-judicial assassinations, I think he would have done a firm about-face on Obama, but not in favor of a GOP guy.
It is inferred in the Old Testament when Jews wearing amulets died in battle and were then prayed into heaven by their surviving comrades. Don't ask me to cite it chapter and verse because I'm not your priest. Find it yourself.
