People are different and they often do not agree on goals or methods to achieve those goals. When they do agree, they form alliances of like minded people to accomplish goals using methods they can agree upon. When those goals and/or methods clash, alliances are broken. Political parties are just one such example of these alliances. Political parties are not empowered by or required by the US Constitution. I have never sworn allegiance to or ceded any of my authority as a citizen to any political party.
I do not believe everyone will ever agree on any one thing. If such a thing were ever to happen, I personally would expect that the apocalypse was imminent.
Libertarian is not the same as libertarian. You probably already know that one is a party and the other is an idealogy. I assume that not all Libertarians are libertarians.
The Electoral College is defined and authorized by the US Constitution. This is the Constitution that many of us have sworn to uphold and defend. The role and make up of the Electoral College has been redefined over time through the amendment process and I would hope that if citizens have ideas on how to make the process better, they work within the Constitutional methods as provided to do so.
Be safe.
