It could be both or a combination of things: -Internal polling may indicate they've been lied to by the media (very demoralizing) -They're having rallies with like a dozen people.  Even the mighty Obama cannot get more than 75 to his campaign events.  -They may be seeing early voting fizzle out with R's outperforming their models and D's under perform.  From everything I've read, this is the case.  If MI, OH, PA, FL and WI are out of reach for Biden, essentially the election is over.    5a00  He has no path to victory. -The slow drip showing the Biden crime family's dysfunction and corruption, may be very demoralizing when volunteers are making phone calls and canvassing door to door.  They may be getting A LOT of pushback from undecided or otherwise Dem leaning neighborhoods. -They may see internal polls that show a significant amount of black and Hispanic support has shifted to Trump, and/or at the very least will not support Biden.
