The woman in the video was complaining that her ballot with a vote for Kamala got lost, and is telling everyone to check to see if their ballot was counted. She lives in a state with mail-in ballots, and apparently has not ever faced the possibility that her ballot could get lost in the mail, stolen by mail thieves (searching for ballots to harvest or destroy), or just rejected because the machine didn't like her signature. As a conservative who used to live in a blue state with mail-in ballots, I knew my ballot was constantly in danger of being stolen or destroyed by people who didn't like the way I voted. It's been a problem for ages. It's just funny that a Kamala supporter would just now be figuring this out. :)
This unlocked a core memory. 😅 I am 45 years old and still remember getting lost as a brand-new junior highschooler on the first or second day of 7th grade, and getting a red-faced, screaming lecture from my history teacher for being late because I got turned around and went down the wrong hallway.
