At this early stage I would caution against throwing the baby out with the bathwater in regards to Mamdani and give the guy the benefit of a doubt. It could very well be that he is the same old and/or an agent of some sorts but it could also be that it isn’t that black and white.
While it may be possible that he's well intended, I'm not holding much hope for many positive outcomes. For one, a $250,000 donation to his campaign was made by Billionaire philanthropist Elizabeth D. Simmons:
Elizabeth D. Simons, chair of the Heising-Simons Foundation (a private philanthropy she co-founded with her husband, Mark Heising, focusing on science, education, human rights, and climate), shares indirect but notable ties to George Soros primarily through aligned philanthropic efforts and political donations in progressive causes. There are no documented personal, familial, or direct financial relationships (e.g., grants flowing between their entities), but their foundations collaborate on specific initiatives and co-support overlapping reform agendas.
Another organization, called the Unity & Justice Fund, donated $100K to him and has direct ties to the Open Society Foundation, aka Soros again. And this is just what we know about.
Are these smoking guns about what Mamdani will actually do? No, not necessarily. But considering his stated stance on immigrants, ICE, etc., it wouldn't surprise me to see New York City devolve further because of his policies. Remember how now-former mayor Eric Adams got attacked and lawfared by the Biden gov. just because Adams was pushing back on all the illegals they were sending there? Well now the Obama faction of globalists, at the very least, have a man running NY who they think will make more allowances for their policies. Keeping NY festering and controlled is very important to them apparently.
Non-Zionist leanings notwithstanding, I think Mamdani's been shunted into office to help usher in more chaos and control, London and LA style. I mean, not only is Obama cozying up to him, but he even shares some of his worst views. And, also like Obama, has seemingly come out of nowhere to take this coveted spot in US politics.
So the non-Zionist thing is just something of a ruse to me ultimately. Yes, the likes of such powerhouse Zionists like Bill Ackman and Michael Bloomberg put a lot of money into supporting Mamdani's campaign opposition, but the Soros peeps have their own modus operandai and agendas of course.
So even if he isn't quite such an incompetent numskull as say, Los Angeles mayor Karen Bass, or London Mayor Sadiq Khan, I do think and fear he appears to be on that continuum, or easily maneuvered to be for all intents and purposes. Though I'd love to be proven wrong.
