You said earlier that even if progressives got someone through on the dem ticket, that they would still lose the general election because liberals would vote republican.
And you need it explained why writing someone in has even less of a shot?
You need to re-read my goal of writing someone in. Yes, getting someone decent through the primaries and hoping liberals support them in the general has less of a shot than demonstrating the Democrat party is non-viable in it's current state by writing in or voting 3rd party.
