There really isn’t much correlation between being a “liberal” or a “conservative” on economic, social and international issues. It’s not just orthodox Jews who often don’t fit into the 2-party holes since we tend to be liberal on economic issues (we like getting stuff from the government), but are conservative on social issues. A large amount of the African American community has a similar problem (they like handouts, but don’t approve of homosexuality, and aren’t happy that aborted babies are disprortionately from their community). Many gays have a problem since while they are social liberals, they tend to be economic conservatives (remember that their “community” lives only for this world, so why pay high taxes for things like educating children or supporting families). Being isolationist or internationalist correlates with nothing else.
If we has an Israeli style proportional representation system, we would support a party favoring social conservatism and economic liberalism, along with a strong foreign policy. In America, there are never more than two meaningful choices since we have a two party system.
