What they've done is scanned the votes too early. They've been preparing the votes for some time and they wait until after the election to see who hasn't voted and then cast those votes for them. That's what happened in the presidential election.
The presidential was different. They likely prepared ballots and already had them in - but not enough, thus the pause and scramble post election. It was just more than they expected Trump to pull.
Recall election is different though. First, they have plenty of time to get them in before and after the election. They know about where they are at based on the mail in ballots already. Notice the lady's age "who already voted" - 88 and likely her friends are all up there as well. When you are running an absentee/mail in ballot fraud op and going to vote for someone you run through the voter roles to see who hasnt voted in the last few, is really old, etc so as to not run into this issue. Maybe they werent too thoughtful in their sample since she probably normally only votes in presidential elections.
Anyway, they know where they are - did you notice after the first few weeks of voting there was massive alarm bells going off. Thats because they saw the early results and woke up. Now see the article above about a cocky Newsome. They are already doing the polling and media stories to support the narrative of a major dem turnout to save Newsome, thus giving cover to getting rid of the recall mechanism and girding up all the dems who are increasingly vocally nervous about the midterms. Of course, they can write these stories because they are ensuring that is the outcome through the ballot stuffing - the media and polling is there so that nobody is surprised or questions it.
Overall, I think the operatives will do a better job this time than in the Presidential, especially in a state where they have almost unlimited control. If its too messy or close I will be surprised. Most dem voters are hive minded progressives who never allow a dissonant thought to flourish within their own minds, much less anyone else they can see. But gun slinging operatives like I was dont usually drink their own koolaide they feed to the gullible, so I gotta think they have prepared well for this.
