even a single day before he dropped out and endorsed her, it was up in the air.
people i know in-person who didn’t see both tweets, when i told them, first immediately reacted with “oh no, now what, they might not endorse kamala, oh god what if they try to give us RFK or something” until i could actually SHOW them that Biden endorsed her. And even then, they were hesitant to believe it.
It’s always easier to say “this was inevitable” after it’s already happened.
