Could RFK running 3rd party siphon off enough votes to save us?
The Democrat primary process is such that the superdelegates pretty much decide whose name will appear on the voting ballot.
RFK would have to run as an independent to ever appear on ballots, and that process punishes independents since every state has different requirements that must be met.
So yes, RFK would take votes, if his name ever appeared on a ballot. People writing him in would take very little away since people don't like writing.
