What media are you talking about? I Googled in Google News for Alexandria ocasio Cortes, and almost all of the coverage I found from mainstream publications was positive.
The "s" page had a bunch of month-old stuff. The "z" page was more recent news. I just rechecked and it's mostly the same way (though we're already in a different news cycle). When I check previously, 4 out the first 5 links were negative. Now, it's 3 out of 6. (Different news cycle)
