This. Voting is essentially always "setup" i.e. the people who make maximum use of the power usually bet on both sides, albeit slightly differently. Since they know it's either one or the other, it doesn't really matter to them who really wins. They have necessary control of the situation no matter what happens.

If you don't frame your life in a way that whoever wins matters to you very less, you are doing something wrong. If that is already the case, your vote doesn't count at all. It's one vote. The chance of your vote actually affecting the outcome of the election is so small that you might as well buy a lottery ticket instead.

If however, you have the power to convince a large enough group of people to sway the election to one side or another, you should sell some of that influence to whoever is offering more money or favors to you.
