Al Jazeera says 62% of Americans want a third party in the United States. No second independent source for this figure is available so far, other than Al Jazeera.
Al Jazeera published an opinion piece examining the historical and structural reasons that make founding a third party in America almost impossible, given the strong dynamics of US politics. The description of the task as 'almost impossible' is the view of the opinion piece, not an established fact.
