Can we just note for a moment that none of the public figures who supported Graham Platner are leftists? They were always liberals who cosplayed as leftists.

Graham Platner supporters:

• Hasan Piker
• Ryan Grim
• Krystal Kyle
• Mike From PA
• Emma Vigeland
• Sam Seder
• ...

As far as I know, none of these people openly identify as socialists, communists, or anarchists.

Calling yourself a democratic socialist or a social democrat doesn't count.

Note: Democratic socialists are actually on the left, but in the United States, everyone who calls themselves that seems to be just a moderate social democrat.
