So how exactly did things get THIS bad for Democrats?

In my entire life I've never seen the party in such a weak, demoralized, and fragmented state. Extremely low overall influence throughout the nation after having lost all branches of govt. A SCOTUS seat shamelessly stolen and there's nothing they could do about it. A presidency basically stolen and nothing could be done about it. Gerrymandered districts which are hurting Dems at all levels of govt. And instead of doing anything about this, it seems like everyone just wants to go back and fight about whether they were for Hillary or Bernie. Hillary vs Bernie is over. Both candidates are too old/damaged to run again IMO and people need to quit blaming, get over it, and focus on the future and stopping the Republicans from destroying everything good in this country.
