Then you should abstain from voting in the present US system because that's not how it works nor how it was designed to work. It's a combative system where compromise is achieved by basically averaging the desires of the interested parties.

This is a Utopian way to govern, which would be great. But it doesn't apply to the US system. If your position is reasonable and the other side is pushing extremely toward their interests you're going to end up with the middle point between you both.

Fine, consider what ever you like. But when you vote you should vote for what directly helps you personally. Giving billionaires tax breaks can't possibly help you in any manner.
I look forward to the day when the US reaches the level of political enlightenment that having an uncle who is a libertarian is as embarrassing a revelation as having an uncle in the KKK is today. There is a reason that this party exists only inside the US and probably couldn't even be sensibly articulated to anyone from another country.
