In the real world, politicians post pictures of them voting for themselves. It’s commonplace. You do not lose your right to vote by campaigning.
Except this is on a much smaller scale. If there were 15 fake voters for you, and one of them were you, then the vote doesn't count. Voting for yourself as a politician doesn't mean anything, it'll be drowned out by thousands of votes. This vote there's only about 40 people actually voting.
