I know and love people who have their South Node in Sagittarius but they are people who are interested in waking up and developing some consciousness. Fairly clear, he is not interested. At its worst,S. Node Sagittarius fully believes they know more than what they do. They make BIG assumptions, talk BIG and constantly exaggerates. Unchecked and combined with some other energies, there is deep bias. An unchecked S. Node also needs to be the HERO.
Mercury(mind/intellect/perception) is weak and in the Sign of Cancer is super-sensitive. It is linked to Neptune, which in its most neuritic manifestation is basically a liar, incredibly susceptible and easily confused.
His second House(values, money and more..) is busy. We can say his value system, his moral core is about money. Imagine, that every choice you make in life is based on money?
Anxiety, trauma from Father is indicated by Uranus in the 10th House. It is also in the Sign of Gemini-mind. Of course, there are ways to work with this energy. One is to feel safe, become the authority. Better-become the ultimate authority. In other words, he absolutely has to be the boss.
Saturn in Cancer conjunct Venus is indicative of an upbringing that was fairly harsh and unloving. For people who are born with this Saturn it leaves deep gouges. They desperately hunger to be loved.
The two luminaries-Sun/Moon are in Gemini,a mutable Sign. This combo is adaptable but changeable. Watching him make so-called decisions this past week, was like watching a tennis match.
He is a bully-Mars in fate degree conjunct Leo Ascendant. Bullies manipulate, they beat you up and then try to soften you when they want something from you.
So, let's summarize. He is a bully, who massively over-estimates his capabilities. His worth/ values forms the basis of his moral core. He is a bigot and a misogynist-Venus conjunct Saturn-unchecked.
His progressed Moon is about to slip into his 12th House in the Sign of Leo. This looks like some heart problems..not surprising. His Progressed Sun just moved into Virgo-more health issues and weary of work. Saturn(karma/restrictions/obstacles) will give his Sun and Moon are hard time in the Summer. More swampy secrets will come to light and tarnish his 'brand.' He will consider leaving.
This post has been inspired by his recent rant about Canada, a rant that was scant on facts and was simply a bully tactic.
