With polls closing, networks are starting to talk about making projections. I found this piece about the changes The Associated Press is making this year really fascinating -- they are going to be more transparent about how they make these decisions and why they might hold back on some calls. These changes are partly in response to the complicated environment in 2020, but they also seem to reflect longer-term shifts -- the evolving media environment has made people expect more transparency, not just a few authoritative networks making calls, and polarization has increased attention to these processes as well.
