She's telling the truth. They'll count the mail in ballots as they arrive. Then the in person ballots. Then they figure out how many fraudulent ballots they need to have Kamala come out ahead.

They need people to think that have this huge number of mail in ballots to process post in person voting. This gives them the time they need to generate and process all the fraudulent ballots.

If they actually counted and reported the mail in ballots when they arrived they would have no time for the fraud because when the in person voting finishes they'd have the numbers.
