I am no astrological theoretician (ha!) but
it seems to be that analysis of *one* candidate's natal chart + a predictive technique (solar/lunar returns or zodiacal releasing or whatever) or even a whole battery of such techniques, should converge to a clear 'great victory' or 'great defeat' when the time around the resolution of the election is examined. (fwiw this is exactly what "Ellen" does in her analysis *in January 2016*, in the Skyscript Forum - link in my post above), at least when traditional astrology is concerned where such a great destiny would be 'predetermined'.
After all if becoming 'king' (or 'queen') is shown as a distinct potential in the natal chart, and the predictive techniques show 'becoming king' then it should be safe to venture a prediction just from the natal chart.
I get the idea that to judge a contest, you ideally want both contestants' birth charts and whoever ends up with the most 'powerful' chart wins. This is a good way if you have both charts. But adopting this approach as 'the way' means that when we *don't* have both charts, we are more or less helpless and might as well go back to flipping coins. (Minderwiz explains eloquently above how the lack of a good birthtime for Hillary eliminates the possibility of accurate prediction)
But if someone is born to be President of the USA ('king' in ancient terminology), and you can't see it in his or her natal chart, then that means that predicting concrete events from natal charts is close to useless. If such a life changing event can't be predicted, then what *can* be predicted from a natal chart?
From what I can make out, we do have *Trump's* birthdata with an AA Rodden rating. Why can't we predict he'd win a great victory in a precise year?
Thought Experiment Time: When Trump was born, his dad calls you, the astrologer, in to look at his newborn's chart. In ancient style he pays you enough to pore over his son's chart for a few weeks or months and come back with a *detailed* reading.
Do you have the chops to see that "In his seventieth year he'll become President of the USA/ or at least 'the most powerful man in the world' after a bruising contest with a female adversary?"
If this can't be done with natal astrology, i.e, such a great victory, or alternatively 'suffers a crushing defeat' as a distinct event in that time frame, can't be foreseen, then what *can* be predicted from a natal chart ? (of course this assumes the traditional mindset, modern astrologers can hide behind 'free will', 'you choose your destiny' etc)
