And as with Guyana so is the USA. The only credible 3rd party is "I didn't vote last time and don't plan to vote this time either". Who will benefit from this is unknown.
I am not going to rule out Trump and I predict that once again the Midwest will hold the keys. The Dems can pile all the votes that they wish in one state, CA, but lose if they don't win the electoral college. If one excludes CA Trump also won the popular vote so the Dems need to understand that there is a world outside of CA, NY/NJ and New England, and should conduct their campaigning with this in mind.
