2. You could call the BoE and ask about their procedure for updating voting history,
but my guess would be they'll update all of that after the election: the natural thing to do would be to use the list of who voted to cross-check the consistency some of the other totals as part of the production of the official numbers
They're really busy now with early voting and preparing for 6 November, so regularly updating individual voter files may be low on their list of priorities
4. I noticed that too - my latest vote isn't there either
I was paranoid enough to check as well. I figured it takes time for them to be recorded in the online system. Or..whatever. Thanks for calling! It's confirmed then.
