Hillary was a bad candidate that ran a poor campaign. She did not pump up the Senate races, she did not excite the base and she was unable to close the election against a reality TV clown. So, now, we fight or we die.
I agree with everything else you said, but want to add one thing. We also have to stop pretending that Clinton lost the election as opposed to all those voters who literally couldn't be bothered to show up. They shouldn't be off the hook, either.
