An audit of what Left and Right media covered that the other side passed on right before the election

\OC\] What Left and Right media covered that the other side ignored, 3 months prior to election

Source: PressAudit asymmetry data. I built PressAudit and generated this analysis from its dataset: [ https://pressaudit.org/blindspots https://pressaudit.org/blindspots

tl;dr: If you follow the news even a little bit you do not need to be told this, you know, you feel it in your bones, but here is the data so you know you aren't crazy. It's pretty obvious whose agenda won the day in the lead-up to the election. Voters were not interested in Hasan Piker, Joe Biden, and Zohran Mamdani.

What this is: These are the top 5 topics covered disproportionately by one side compared to the other side by week, ranked by the number of weeks that topic was at the top. Showing the ten most recurring topics on each side from August 3 to November 1. Think of this as like the Billboard top charts for media attention.

“Ignored” is relative here, not necessarily zero coverage. This chart only lists topics where one side's coverage is way above its usual one. While I saw Left media covering things like Data Center Policy \~2.5X more the Republicans, this focuses specifically on the absolute most outsized differences in one sides agenda, week over week, vs the other's.

>If you are wondering "why is there no Trump here": Left outlets write about 19 Trump articles for every 10 from the Right, compared to about 14 for every 10 on all topics, so Trump's lead is not much bigger than the Left's usual lead. This chart only lists topics where one side's lead is well above its usual one, and Trump falls just short.
