Polys, Henos, and gods from another universe?

Are Mormons polytheists (worship many gods) or henotheists (believe in many gods but worship one), who in the case of Mormonism used to be a Mormon male from another planet or universe who lived a good life and is now being rewarded by his godhead and the worship from many others?

Since there is a possibility that a Mormon may be the next President of the United States, I believe this is a valid and important topic.
