Libertarianism gets marginalized in American politics because it doesn’t fit into the two-party paradigm. Libertarians want less state intrusion into the market, which aligns them with Republicans, but also less interference in social choices, which aligns them with Democrats. As Massachusetts governor William Weld put it in 1992, "I want the government out of your pocketbook and your bedroom." To the partisan brain, this doesn’t compute. "In 1976, people didn’t have the vaguest idea of what I was talking about," says Ron Paul. "Why was I voting with the left sometimes and with the right other times?"
