These candidates are really the only challengers to Biden in the primaries. All of their campaigns are extremely long shots (but not impossible in my opinion- if we decided we liked them more than Biden they could win). Let's all have a civilized discussion/debate over them. Let's try to not focus too heavy on their perceived inability to beat Biden but focus on them as actual candidates.
my take
MW: I recently watched an interview with Marianne Williamson who I'd never heard of before (I'm sure there's a reason media doesn't cover her). She really impressed me with her views, especially on neoliberalism. She heavily reminds me of Bernie and isn't running just for the sake of it or as a protest like some other long shot candidates do. In my opinion she deserves everyone's vote in the primaries, at least. She is also very talented at oration.
CW: I'll be honest, I know very little about him and need to do more research.
RFK JR: He's literally a clown. He's a nepo baby and all his views are inconsistent, harmful, and crackpot. He has no shot at winning.
There's a reason why these crackpots have no chance at winning
