I am somewhat befuddled by the 5 corrections in a row...
The only time your vote directly matters is when it creates or breaks a tie.
Elections that are tied, or 1-off being tied, are very rare.
However (!), one allegedly just happened:
In the 94th Virginia delegate race of 2016,
Democrat Shelly Simonds defeated Republican David Yancey by a single vote
11608 to 11607.
But then a 3 judge court ruled it actually was a tie: 11608-11608.
This was because Yancey's team
found a single extra ballot which had not been counted
because it had been judged "ambiguous" due to voter filling in both
bubbles. But the voter also had slashed a line thru the Simonds bubble.
The 3 judges believed this meant the voter had intended to vote Yancey.
To break the tie, a random choice (e.g. coin toss) will be made!
Even more amazingly, if Simonds wins it, that will create a party tie
in the legislature, while if Yancey wins it the Republicans
will have majority control of the legislature.
Perhaps it should have been argued that 1 voter meant Yancey with
probability 2/3 and meant Simonds with probability 1/3,
in which case Simonds should have won by 2/3 of a vote!?
I mean, I do not think it was 100% clear the voter meant Yancey, and
any percentage below 100%, such as 99%, "should"
have been regarded as a win for Simonds... right?
Anyhow, usually whenever it is a tie or near-tie, the amount of
voter errors and other screwups is large. I do not believe in
claimed accuracies better than 0.1%.
