Can a Christian vote for either Presidential candidate?

As a Christian, I’ve had a lot of people coming at me with reasons I should or should not vote for a presidential candidate from a spiritual view point.

After looking into the core beliefs and actions of both candidates, it is my opinion that if you are voting on a spiritual basis… you cannot vote for either one.

Here is just one example of why I feel that way:

McCain states he is a Christian, a member of the Baptist church. However, McCain carries around a “lucky” penny, nickel, quarter, feather (given by a Native American shaman), compass and four leaf clover. He has a “pouch of sacred stones”.

He also brags that he is superstitious. He knocks on wood and won't put a hat on the bed (bad luck). He refuses to pass a saltshaker from hand to hand. He has lucky shoes, sweater, hat and even food.

Obama states he is a Christian, a member of the Church of Christ. Obama carries around a "lucky" poker chip, eagle pin, and a statue of a Hindu god. The only superstition I could find that Obama practices is playing basketball before a primary for good luck. ??

Charms are defined as: An item worn for its supposed magical benefit, as in warding off evil; an amulet. An action or formula thought to have magical power.

Both men have stated with their words that they have placed their faith in Jesus Christ.

Both men have shown with their actions of carrying "lucky charms" and believing in superstitions that their faith in Jesus Christ is not strong enough to overcome believing they need to also have faith in a man-made object (called an idol in Biblical days) or ritual over the power of the Living God.

Isaiah 44:17
From the rest he makes a god, his idol; he bows down to it and worships. He prays to it and says, "Save me; you are my god."

1 Corinthians 5:11
But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.
