Let's look at the facts. In his time he was an inspirational and charasmatic leader who could gain people's support, so anyone who voted for Obama for simular reasons has no room to criticize him. Secular sources confirm that regardless of his divine status, he did in fact exist. Now, if he is the son of God, then he can do no wrong, and if you are going to vote for someone who CAN do wrong over someone who CAN'T, then what are you looking for in a candidate? The ability to be evil?
If he does have powers from the big man himself, then he can literally conjour anything into existence. Spend billions of tax payer dollars cleaning up the slums? BOOM! Jesus can make them into streets of gold. Healthcare plan? Jesus can heal anybody of any illness! What's not to like?
Now, if he isn't the son of God, then he is still a man of morals who does his best to stand up against oppresive government. You wanna talk about seperation of church and state? Jesus was put to death because there was no seperation of church and state. You guys are on the same page.
Don't let religious people ruin religion for you. Jesus becoming president isn't going to force you to be part of any religion or go to church. You may not agree with what we assume his policies are, but that's no reason to attack anyone.
It's assumed Jesus would be anti-abortion. This isn't because he is a strict old person who wants to ruin our fun. It's because he believed all human life is precious. That sounds like a good quality for a leader.
Christians are also notoriously anti-gay marriage. This is because the Bible speaks unkindly of homosexual actions. However, the Bible is also against tatoos. Why is that? Because at the time, the pagans were heavy on tatoos, and, at the time, Christians needed to distance themselves with Pagan traditions. Who is to say gay marriage isn't in the same boat? I'm Christian, and I have no moral issues with homosexuality.
To wrap things up, other issues mostly believed in by rednecks, but are associated with Christianity in general are no free healthcare, keep immigrants out of America, bomb terrorists, even being anti marijuana. Nowhere does it say that God is anti-free healthcare, racist, war hungry, and would never toke up. This is all assumed.
If anything, Jesus coming back to run for president would give him the chance to set the record straight.
