Ed Schultz for example describes himself as follows:

Ed Schultz, one of the best-known and most well-respected progressive commentators in America, has joined RT to host his primetime news program at 8 pm EST weeknights. The political journalist is discussing the most controversial issues affecting Americans and gives a platform to diverse voices, stories and perspectives to viewers.

Likewise, Glenn Greenwald has been described as left-wing and progressive. That being said there are folks who claim to be progressive who push for the following goals, which overlaps with many of the goals of the alt-right:

* A desire for better relations with Russia.
* A belief that U.S. elections are not legitimate and are rigged.
* Attacks on trade agreements as victimizing the U.S. economy.
* A resentment of "establishment" Democrats and Republicans who are only seeking to promote the interests of global elites.
* A belief in a conspiracy by a shadowy deep state that is working to promote the interests of global elites and seeking to promote a war with Russia.

I can post any number of examples of "progressives" and "alt-right" commentators espousing these talking points. This is why I wonder whether a new Third-Way or No Labels movement will be created to attack and undermine "establishment" Democrats and Republicans with claims that the U.S. Democracy is irreparably rigged and that the media is inherently corrupt and prone to the distribution of fake news.
