Bernie likes loyalty and has a blind spot for people who support him, so I don’t view reciprocal endorsements from him very highly. He also brought Tulsi Gabbard in and she was rotten way before turning to Trump.

Platner himself endorsed Jackson though, so hopefully they’re more aligned in outlooks.

I really don’t know how someone goes from being the most insider of insider politicians to an outsider populist without it being an opportunistic move though.

I think the really important thing is that if he drops out, Platner decides his replacement. Anything designed by establishment insiders is going to reek of an establishment coup. Even running a new primary is questionable because it takes time for an outsider to establish themselves as a viable option. People reliably just rank names they know when asked out of cycle who should be the next whatever.
