Barbara, you pretty much nailed it. What was the first red flag for me was about Hillary's chart before Trump even declared (I think). These two factors were brought to my attention by others ...
You don't even need a birth time to see (a) Moon in Pisces - no U.S. President has had that placement and for good reason; (b) Saturn closely square her Nodes (and Mercury)- by itself not prohibitive, since Woodrow Wilson also had the aspect, but when added to the Moon in Pisces signaled problems.
I don't think Democrat & left-leaning astrologers (I'm one, a Green Party member) wanted to look at Hilary's chart objectively against a backdrop of research and learn something. The largest portion of U.S. Presidents have had Moons in earth signs, giving them practical ability and a tendency for factual, material clarity Hillary lacked. Not a single U.S. President has ever had Moon in Pisces. Someday that will probably change, but only when the office itself changes significantly. Even then the particular president will have Moon aspects that help overcome the innate tendencies of Pisces.
In addition, a survey of U.S. Presidential charts will show you Mercury aspects are important and many of them have multiple aspects with Mars, Pluto, Jupiter, etc, enabling effective communication. Hillary's Mercury 21 Scorpio-Rx squares her Saturn exactly. The wider conjunction with Venus simply doesn't rescue it, and the wider square separating from Pluto only serves to intensify it.
So there were fundamental astrological problems with a Hillary candidacy from the start. Those made it easier to expect Trump in the White House. So I was not surprised, just in a degree of de-ja-why? for a while like everyone else.
The answer to why us U.S. karma, which means hard lessons learned the hard way in full dramatized view of the whole world so that it is witness and we cannot go head-into-sand later about it. There is a great portion of the nation (south, midwest) that is still stuck in old segregation civil war thinking. Only this time the conservatives-rise-again types are grabbing hold of the levers of executive federal power they've condemned as over-expanded and will lose many of them in the long run as the new battle of federal vs states shapes up. I had previously referred to this as the Great Divestment, but didn't think it was coming quite this quickly. There may be a better name for it, but this is the beginning of fiscal divestment in the states by the federal government and the assertion of state and local power, which will ultimately define 'citizen' more than any federal law or agency. Its called Jeffersonian Democracy.
