I'm fully aware, I don't know why people vote for either party. Or why certain people are feel the election was "stolen" because it didn't matter who you voted for.
As long as you know that both sides care most about not making the money sad, there are some distinct differences between the two.
The reason people don't vote third party is due to lack of game at the lower echelons of government, rules that make funding third parties difficult, and the shear math of how our voting works.
Like, the Libertarian Party doesn't go for state reps or mayors or ombudsman, or dogcatcher or whatever. They only throw shots at the big show with zero institutional support, where even if they won they'd get nothing done because they have zero backup in any other part of government (which is good in this particular instance, because US Libertarians are fucking batshit)
