This post is on Madonna, but using her Virgo rising chart as many still believe that is the right one (I still see her as Aquarius rising because she has the aloof look, yet doesn't have any Aquarius in her and Uranus isn't conjunct the Sun, Moon, or ascendant).
Leftist- Venus square Neptune, ruler of Venus Sun in 12th house trine South Node
Rightist- Venus square the Nodes
Leftist- Moon sesquiquadrate South Node, ruler of Moon Mercury sextile Neptune, ruler of 4th house Jupiter conjunct Neptune
Rightist- Jupiter conjunct North Node
Libertarian- Pallas ruled by and conjunct Sun
Authoritarian- Pallas trine South Node, Sun conjunct Pluto and trine South Node
Fiscally and socially to the left, aggressive Pallas- Left wing authoritarian
Regardless of the chart, her liberal politics are still very prevalent.
