Ron Paul would like to legalize the optional use of silver and gold in the US. He believes that Constitutionally there should be no taxes or confiscation on gold or silver and that the free market should make the choice. (The Fed will fight obviously this, because good sound money always drives out bad and the FRN would be obliterated.)
Disclosure: Ron Paul canvasser, and long both silver and gold, however I am against an IMF or government forced gold standard.
