There is a difference between neoconservatives and neoliberals. You probably meant the latter, but Republican party was never neoliberal only, it also is, as you write, neoconservative.

It's not really surprising as conservativism and liberalism are both main pillars of capitalism, because the idea of property is based both on authority (like authority, you get the property ostensibly based on your past performance and you keep it indefinitely) and liberty (you can do what you want with it).
