I also doubt either channel can define communism or jihad correctly.
"Communist" in American political parlance is just a synonym for "Democrat" and has been since the days of the New Deal.
For an US perspective, yes. From an European perspective... him and Bernie are center-left, if not centrist. The Overton window is positioned much more towards the authoritarian right in the US than it is here - although the huge amounts of American and Russian funding towards far-right parties have been shifting the window here as well for about a decade.

It really isn't rocket science lol
Mamdani seems very proud to be a socialist and you get a taste of it where he says "...the end goal of seizing the means of production, where we do not have the same level of support at this very moment" and "..we have to continue to elect more socialists and we have to ensure that we are unapologetic about our socialism", etc. He is very clear about his beliefs.
I've seen this dude described as an "islamo-communist" more than once in different countries' medias (not fringe medias). I presume "islamist" because muslim, and "communist" because he's left of the center-right. You can't really talk with these people anyways, they're too far gone
