Me clicking the wrong option just did not happen in this case. I know this because it was (according to the graph), the very first vote in the poll.
My vote showed up as 100%, and the site said that one person had voted, and that I had already voted.
A few minutes later, my voted option is shown as 0% and there are three votes, and I'm told I have already voted.
And .... both of those options were a bit further down the list than the one for which I voted.
That's just weird and creepy. I may be on drugs, but I know weird and creepy when I see it .... and my left hand is starting to hurt .... must stop typing for a few hours.
