"RFK Jr will not sell out. "

I'd be a lot more convinced if he ran as an Indy instead of a Dem. Granted, Bernie is still nominally an Indy. But he ran as a Dem. If RFK ran as an Indy, he'd show that he plans to be in the race until November. If he loses the primary, he's out for the count.

West, just by running as third party, is showing more comittment. Apparently he learned from Bernie's fuckup (both times).
