There were three types of Democrats who reacted in three ways to Biden’s debate collapse.

1. 
   Democrat insiders who had been around Biden and knew what to expect
2. 
   Ordinary Dems who had limited confidence in him and thought he was too old
3. 
   Highly active liberals who donate and consume a lot of media, and genuinely believed the lies.

Of these three groups, only the latter were truly shocked, outraged, and made frantic by the debate. This however is also the group at which much of the media’s political analysis and fundraising is aimed.

Their panic helped touch off a mostly disorganized effort to dump Biden.
