I really wonder if the Libertarians do actually start to make real gains as Gen Z begins voting. They are pretty Libertarian friendly, even if there’s a large segment of them that Lean Democratic.
They'll take a chunk of the Republican-leaning electorate in the age group, which is much smaller than the Democratic electorate. Your typical young libertarian voter (in my personal experience, not saying it's exhaustive) is usually either someone who grew up wealthy/upper middle class and doesn't understand why people worry about paying for healthcare, or, weirdly, a lot of people in the military who also don't have to worry about healthcare or college and thinks cutting government waste won't apply to them. Also your random gems who think abolishing the ATF/child labor laws/minimum wage is a good idea. I see their ceiling as 5-10%. Most young people are either progressive or liberal.
