Some things in there that might turn someone who is typically Republican or conservative off of the Libertarian Party (and therefore the Libertarian Party's candidate):
• No restriction on abortion.
• Gets rid of foreign foreign economic and military aid (which I'm assuming would include getting rid of aid to Israel, which is why I think it would be a problem for Republicans).
• Calls for close to an open borders policy (exceptions being for people who pose a creditable threat to security, health, or property).
• Full legalization of most drugs.
Some things in there that might turn off someone who is typically a Democrat or liberal off include:
• Government should not discriminate on the basis of sex, wealth, ethnicity, creed, age, national origin, personal habits, political preference or sexual orientation, but private parties can. Those who disagree with a private party's choice to discriminate can respond with ostracism, boycotts, and other free-market solutions.
• No minimum wage.
• Implied elimination of public schools. (Education best provided by the free market, and government should not compete with private enterprise).
