Sanders didn't lose the primaries based on policy, and in fact I still haven't seen a good argument from Biden supporters why his platform is better than Bernie's. He lost because everybody was so terrified about this electability thing, and decided to vote for this empty suit candidate instead of the scary socialist. Look, I like most Bernie supporters sucked it up and cast a vote for Clinton in 2016, but honestly I don't see much of a point in doing that this time, because I don't feel like jumping on a sinking ship to demonstrate my loyalty to the party will be worthwhile, especially because I don't live in a particularly competitive state.
