I'd disagree with most of those. European-style socialists haven't been allowed in American politics since the Red Scare of the post-World War I era. They were much too useful as a scapegoat in the successive years, being thought of as spies, turncoats, anarchists (strangely enough) and terrorists. Of course, as Victor (shockingly) correctly alludes to, this is due to the enormous power of capital within the United States compared to Europe.
European conservatives don't really have an analogue in the US, because the US traditionally doesn't value centralization of power, preferring devolution to state and local governing authorities. The only major intersection is the opposition to nationalization that both groups have - however, European conservatives don't support deregulation in the same way that American Republicans do, thinking it too "dangerous". They might correspond with Democrats here more than Republicans.
However, European liberals I would say are much more confluent with the power centers of the American Republican party. Neoconservatives here are neoliberals everywhere else in the world, or what they would be if they had the big cash trough of a military that we do.
Hope not to offend anyone, but the Green Party is so insubstantial in the US as to not warrant consideration, and will remain as such due to the intolerance the two-party system has for wildly divergent viewpoints.
