After watching Fareed's show yesterday, I expect Trump to declare himself the winner on election night based on early returns that almost always favor Republicans. A few days later, that will change and it will be clear Trump lost. Chris Wallace and John Roberts (Fox White House correspondent) better come heavy on election night at Fox. They might be the only two left at Fox who can tamp this down.
The most important thing all commentators could do is to preface every results update with the phrase "With just XX percent of the votes counted, ....". Make clear every time that it's not over until it's over.
