I believe this is overly simplistic.
Our media does a horrible job of informing people. We live in such a visual society, so everything is based on quick video clips and clicks. Media outlets are hurting for money so a lot of journalists are out of jobs. Media corporations are seeking quick and easy hits. Their job isn’t to inform but to direct traffic to their websites and social media outlets. So even if Harris wanted to sit down and talk policy, the media outlets wouldn’t do a good job actually drilling down into policy. I recently read a piece that many journalists who follow politics don’t even care about politics. To them it’s no different than watching sports or reporting about a game. A media that prioritizes access and clicks and relies on video, cannot effectively inform the populace about candidates and policy.
The other issue is that the population for the most part, doesn’t actually care about policy. And it hasn’t cared for quite some time. It’s all about vibes.
