Moderators are Democrat: Mostly no. Chis Wallace definitely isn’t.
Journalists are Democrat: Mostly yes, but editors being mostly Republican puts a crimp in that.
Fact-Checkers are Democrat: Not sure, but they mostly *try* not to be partisan. Some are bad with both-siding everything.
Pollsters are Democrat: See Fact-Checkers.
Athletes are Democrat: Mostly yes. I’m not sure if they have any real influence on undecideds though, and some of them risk their careers for seeming *too* liberal.
Entertainers are Democrats: Mostly yes, always have been. Most conservatives are terrible at entertaining.
Big Tech is Democrat: Mostly no, they’re usually libertarians or technocrats who aren’t fans of either side.
Corporate America is Democrat: They’re for whoever is likely to be the bigger short-term financial benefit. Short term-benefit says for most of them, Biden is good, Trump is bad.
