Sounds like you're operating under some kind of premise that Harris should get as many votes as Biden even though Harris is wildly unpopular and the Biden administration fucked up the entire economy. In 2020 everyone came out to vote against Trump, that same level of enthusiasm is nowhere to be found.

Also California alone is about to give Harris 4M more votes.
I really don't understand what is so hard to get about this.
Simply wait for all the votes to be counted first before making these accusations.
