Whats the most Liberal political party in the United States.................?

There are no liberal parties, all the parties are far right with a variation the size of a gnat. The truth is we have the choice between the colors dark red and dark dark red. Its like George Carlin once said, "The only choice we have in this country is 'Paper or Plastic?'" Its all just an illusion of choice, the parties argue to give the sense of opposing opinions, but they are all the same.
