@hightor,
Note that Warren didn't fly either, so here goes your advice. No, I think the people just got fooled by the 'system' into being oh-so-scared of any significant change. You included. And now of course you have buyer's remorse and you wish that Sanders' ideas would somehow stick, right after you gave them the boot in the ballot box...
It's a missed opportunity. Washington will remain fucked up for the foreseeable future. Even if Biden wins, it's not going to change much. You'd have one less corrupt madman at the top, but many more waiting for their turn in the shadows.
