So Galon is basically like the Meretz equivalent to Hillary Clinton, and Gilon is more like Bernie Sanders?
Gilon is way, way to Sanders's left, much closer to traditional communist economic views than most self-declared socialists are today (while Sanders is on the right of socialism). And Galon is well left of Hillary Clinton, probably closer economically to Sanders. Meretz in general is far to the left of the Democratic Party (it is, after all, a party that could command no more than maybe 10% of the vote in Israel at absolute maximum, the total it got at its peak in 1992).
