I will downvote Glenn Greenwald without exception because I consider him to be a fascist. The times when he makes good points are straight out of the fascist playbook of stealing leftist points to redirect people into a fake version of class struggle. In his case, it's a rather obvious struggle to portray the democrats as "actually worse" in order to get Trump elected without ever explicitly supporting Trump - a perfect mirror image of CPUSA's "vote against fascism" campaigns.
I don't know or care whether Glenn consciously supports Trump in his own mind. Nor do I think it invalidates the good work he did a decade ago. People like him, Nick Brana, Jimmy Dore, and Russell Brand will always claim to support a third party, but what they're building isn't a communist party connected to class struggles; its a rebranded Intellectual Dark Web. If you want to see this laid bare, watch Jimmy Dore criticize Cornell West the second he mentions Donald Trump, but as a "progressive": https://youtu.be/vv9WUBuahsY
People will interpret this as me saying you have to vote democrat for harm reduction and reflexively downvote, so let me just say I'm a member of a communist party that runs a 3rd party presidential campaign.
