I don't have the same algorithm as others, and if I did, it would be good enough to choose one of us at random to be responsible. Taking votes from everyone would be highly inefficient.
No. First, in case of humans this works by approximation, not exact copy. Second, you don't know what is the group of people who think in a similar way as you (clearly not all voters).
If there's such a small chance of your vote making a difference in the election, you should be comfortable voting for trump.
