One of the net results of the failure of the Bernie Sanders campaign was the radicalization of his base. It radicalized his base in both directions, and you can trace the history of some people's right-wing and left-wing growth to the collapse of his campaign. His campaign brought a critique to the masses that really hadn't existed for more than a generation. You can see the sentiment growing with the frequency of crises. 9/11 and the War in Iraq, the 2008 housing crisis, the rise and fall of Sanders, the Trump presidency, COVID, the fully botched and bungled Democratic Party presidential campaign coupled with Palestine, on top of another Trump presidency. Each crisis is like breaking a pinata full of minds looking for answers and ideologues scrambling to scoop them up and provide those answers. People who were not "political" before Mamdani will become "political" because of Mamdani. The people working in his campaign (nearly 30,000 canvassers alone) will be exposed to organizing, become political agents, and will likely adopt some of his perspective or maybe join the DSA. From my reading, the campaign made the bar extremely low for people who wanted to participate, allowing for people to give as much or as little time as they could, on their own schedule. These are valuable lessons to be learned from his early success. Most of his canvassers are young, early to mid-20s, and Sanders failure was 9 years ago. The people energized by Mamdani (who was 26 when the Sanders campaign fell apart) could develop similarly to Mamdani but at a more accelerated pace, given the existing development already; these are objectively good things; this is the result of these qualitative changes.
