It seems that Michael Rectenwald now supports Trump. I remember on facebook a couple of years ago he was well-respected by some leftcom/marxist people (I too found his comments often sound). Here are some of his articles:
It seems he started an "experiment" to pose as a friend of the rightwing (on twitter, apparently also setting up a newssite "Citizens for Legitimate Government"). I did not really understand his explanation for that (which he gave on some self-described Marxist podcasts).
So what is happening? Why this silence? For example, the usual source on latest scandals on the left, Ross Wolfe's Charnal House blog, has not been active for over two weeks.
There are several "leftists" who more or less openly support Trump. I think Dennis Kucinich falls in that catergory. One leftist-Keynesian blogger, though vehemently anti-marxist, calls for an Altl-left. Perhaps not such a surprise though, since "Keynesian" etc. money cranks are basically populist-nationalists (see also prof. Werner, or revleft forum user DieNeueZeit).
