DNC pollster suppression in 2024 election

https://youtu.be/snBfQTcazrY?si=xp1QwMNngRGpJbZP

at the 0:50 mark, vaush starts talking about DNC pollsters during the 2024 presidential campaign who were instructed to effectively disregard criticism of Israel and mark it down as “other” or “no response.“

I’m having trouble finding an article regarding this. By no means am I questioning whether or not this happened, it is 100% in line with the DNC and Dem leadership goals, and Vaush isn’t the only commentator I’ve heard talk about this.

This was the most relevant I could find on this specific issue but it doesn’t exactly refer to marking Israel/Palestine as “other/no response.”

Does anyone have a source for this? Or at least have an idea of where it came from? Article, interview, tweet?
