Nothing like this steady stream of former staffers coming out against a president has ever happened before. Don& #39;t expect any direct effect, but as with cross-party endorsements by politicians it has indirect effects. https://twitter.com/AaronBlake/status/1306685651484639232">https://twitter.com/AaronBlak...

Indirect effects: (1) Each time it happens at a high enough level it& #39;s a story, which doesn& #39;t last long but it& #39;s a bad-for-Trump story that bumps any potential good-for-Trump or even neutral stories.

(2) There& #39;s surely a cumulative effect on "neutral" journalists. Their strong instinct is both-sidesism; these defections make it more clear to them, and "safer", to treat Trump& #39;s unfitness for the job as an objective fact, rather than trying to stop themselves from doing so.
