In process of doing my "day job" I interviewed an individual (who will remain nameless) and asked him what he thought of Joseph Smith's platform when he ran for president. This individual is a Mormon enthusiast/apologist but is not a member himself. He has read and reviewed over 500 books on LDS doctrine, history and even a few LDS fiction stories. Some consider his opinion to hold considerable value.
When Joseph Smith ran for president in 1844 he published a pamphlet or tract called "Views of the Powers and Policy of the Government of the United States". Many have not read this tract today but it was widely circulated in his day by newspapers and by the council of 50 (missionaries called to proselyte Joseph for President). (Views .pdf available here) This gentleman's response when asked about this tract was that the writings are very different than what many might expect. He concluded that the pamphlet "represents a liberal view on government that many Mormons would not be willing to accept today."
Perhaps this is nothing people will comment on, but I wanted to get the pamphlet out there for people to read and to become familiar with. Few documents exist where prophets or apostles make commentary on political principles and topics of proper governance. By no means do I consider this doctrine, but something worth the read for those who are LDS and politically minded. Then make up your mind, was Joseph Smith a liberal, a libertarian, or somewhere in between?
