I have ZERO confidence that my ballot is being counted correct by the machines tabulating the ballots. I have ZERO confidence that there are not boxes full of pre-marked ballots waiting in someone’s trunk to be produced if the tally starts going the wrong way. I have ZERO confidence that there is any way to audit the vote totals and confirm that they are a reasonable reflection of the intent of the ballots the voters filled out. I have ZERO confidence that only legally permissible voters are casting ballots. I have ZERO confidence that only legal voters ballots are counted.
So why do I vote? Just doing my part in making the margin of victory larger than the margin of fraud. If the nation ever has to resort to the fourth box of democracy, I can sleep comfortably at night knowing I did my level best to use the first three effectively, and the bastards had it coming.
