Last month, Rod Silva announced that he has formed the Nutrition Party and that he will be its 2016 presidential nominee. He has since qualified to appear on the November 2016 Colorado ballot. Here is the campaign web page. Silva owns a restaurant chain that is focused on only serving healthful food. So far he does not have a vice-presidential running mate.
The Prohibition Party has also already qualified to appear on the Colorado ballot for President. The ballot-qualified parties in Colorado are Republican, Democratic, Constitution, Green, and Libertarian.
Have any other candidates filed in CO yet? I couldn’t find a list on the SOS’s website.
