There should be no surprise that Disney has killed the rest of the staff of 538.
Nate Silver (Silver Bulletin formerly with 538), Nate Cohen (NY Times), and Harry Enten (CNN formerly with Vox) continue to be the only people who speak with any basic Statistical knowledge in terms of polling on the news.
Unfortunately, the best source of aggregated pure data is gone. I used to use it weekly with my class to math check politicians.
At this point, Nate Silver Bulletin is the only place to get some polling averages. For all of the ignorant sh!t Dems talk about him when they are losing or GOPers give when they are losing, he continues to on the nose with his math.

Along with the death of Vox, it's hard to get good data to teach my students how to be math-savvy about their news.
