It's indicative of how much confidence Dem donors have in the currrent Dem leadership.
NOT MUCH.
Which is why they need to keep lying to them.
With the Trump win, they told their sheep it was because of Russia.
When GW won first term, it was because the SC handed him the election.
When GW won his second term, it was because of Diebold and other things.
As long as they can keep convincing their idiots that they actually won, but got cheated somehow by the Republicans, they maintain their confidence. As you pointed out, now that confidence is running out and they are coming face to face with facts: Americans don't want a Socialist government.
