If you're asking why we downweighted the submission, moderators routinely do that on HN when a story doesn't fit the site guidelines, isn't substantive enough, is overly sensational, and so on. If we didn't, HN's front page would consist of the same few hot topics and flamewars repeated over and over. Maintaining a site for intellectual curiosity requires active pruning.

Sure, we've routinely downweighted tons of election campaign stories, which is what most policy proposals from candidates are. That includes Elizabeth's among many others. I could see making an exception for proposals that come with detailed arguments and make a genuinely new contribution to debate on something that's on topic here. But most aren't anything like that, they're just attempts to gain attention for a candidate.
