Because Charlie Kirk was a carnival barker and not some legitimate grassroots hero or whatever it is chuds think he was. Yeah he took money from Foster Friess and other ghouls and he did "organizing" and "outreach" by arguing in front of college students. But at his core he was a sideshow selling t-shirts.

The billionaire class that invented Charlie Kirk still exists so of course his death had no impact on wider politics. Because he never mattered. Furthermore I'm not convinced the average person even knew who he was before he got ventilated. I remember even my most chuddish coworkers saying they hadn't heard of him.
