I'd ague that captured opposition means the real fight starts within the DNC because its a big tent party and one of the biggest factions are Republican appeasers.
Its up to Dems to decide if they need to reform the party or make a new one, but the idea that voting blue will bring the change you want. It won't. The real fight starts with party governance and candidate selection.
The first is to be used.
The second is to restore the 1st in the event it is damaged.
The third are to restore the first and second in case the building burns down.
Publishing is a racket. This should have been done decades ago.
