the only person who will be helped by my vote is the person for whom i vote. the only vote that helps trump is a vote for trump. i won't be voting for trump. my vote will not help trump. qed
you won't be able to discourage me from voting. and you aren't likely to convince me to vote for someone unless i want them to win. of course, i could be bribed, but i doubt anyone wants to pay $20,000 for one vote.
