My idea for a progressive 3rd party

[Pat Mustard]

The problem with your positioning of the 3rd party Won2blv is that, institutionally, there's no left in US politics (even St. Bernie is Labour right in the Blair mode), you've just got the Tory right (protect traditional way of life), and Whig right (no government regulations). In economic terms both parties are Whig but in social terms (including maintenance of class divides) the Repubs swing hard Tory.

Introducing a third choice between the two is meaningless, as it'll quickly devolve into a clone of one or both. What is needed in US politics is a proper left leaning party.

You can't have a left leaning party until people start swaying that way. The GOP has owned the messaging in America and the Democrats have been cowards. Democrats need to start with getting people to listen to them first

You can and you will, if you've got someone to communicate it the right way. Look how close Bernie got to the White House, and he wasn't even particularly clever with it.

And going back, look how scared the establishment within both parties were of Huey Long, because he was able cloak his socialism in language American people were comfortable with.

Just as the US is more receptive to fascism than most people would guess, they are also more receptive to socialist ideals disguised as something uniquely American.
