There are many people in both parties that are Libertarians at heart, but they think that government is answer to "enforcing" liberty.
For instance, I was a Democrat, and in many ways still am, but I always supported Gay rights, Public Education (not in its current Communist form), Marijuana use, closing Gitmo (wtf happened to this Despotcrats?), pulling our armed forces out of all foreign countries [except a few overseas bases] (also wtf happened to this Despotcrats), ending the Patriot act (wtf happened Despotcrats), etc.
Many Democrats believe they can use government to LIBERAT(-arian) people, but they don't realize that removing government altogether from the process is best, except for the most BASIC anti-discrimination laws. We can derive this from Thomas Paine's Common Sense:
will point out the necessity, of establishing some form of government to supply the defect of moral virtue.
Here then is the origin and rise of government; namely, a mode rendered necessary by the inability of moral virtue to govern the world; here too is the design and end of government, viz., freedom and security. And however our eyes may be dazzled with snow, or our ears deceived by sound; however prejudice may warp our wills, or interest darken our understanding, the simple voice of nature and of reason will say, it is right.
Now if we look at the 15th Amendment (without analyzing conspiracy theories associated with it and the 13th and 14th amendments, in which I do believe in, but that's for another discussion), it fits in quite nicely with the Thomas Paine narrative:
The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude.
Notice it doesn't prefer a specific color or race, it just says, in general, "race" and "color."
This amendment makes MOST (not all) of the anti-discrimination laws unnecessary, which are designed to help specific groups. Some discrimination laws are also passed with very evil ulterior motives, for instance, violating the right to contract, or forcing private citizens and business to abide by certain behaviors and thought patterns. That's when shit gets ugly.
I would amend the 15th to include religion or, quite vaguely, any other category of distinction. Vagueness, albeit unusually, would actually work in the favor of the People instead of against them in such an Amendment.

Anyway so what's the point of this entire post? Most Democrats are Libertarian within their souls, they just DONT KNOW they are being fooled.
The same applies to most Republicans. Again, they just DONT KNOW.
The propaganda/media/psychiatrist-complex, which was very successful during the rise of Fascism (and Communism) and instant/mass communication, discovered how to TAP into every person's "evils" and to make them vote in a way to enrich themselves and hurt others, while in the end, all we end up doing is hurting others and ourselves, without knowing it, and then we blindly blame the other side. Lakhota is prime example of this, and sadly, many many people are like this. They just don't realize they are being scammed.
