Zodiac Sign Found Most Among U.S. Presidents, by Corrine Lane.
Graphs and observations on US Presidents to date (with 4 listed exceptions) are grouped into:
Because there's no time of birth available, as yet, for Bernie Sanders it's not possible to compare his data as regards mid-heaven and rising signs. His Virgo Sun and Aries Moon are not especially favoured, but MC and rising could balance that. I'm hoping for Cancer inclusion at rising or MC!
Hillary Clinton has Scorpio rising which isn't beneficial at all, according to this study.
Is Scorpio Rising So Scary?
Not even one U.S. president has had Scorpio rising. I have 3 theories about this. First, it may be that U.S.A. doesn’t want a sexy president. Second, Americans aren’t ready to trust a president that is so predisposed to extreme secrecy. Scorpio Rising people appear to be hiding something even when they are not. It’s been said that Scorpio Rising generates fear in others. (Scorpio’s secrecy is really just a protective instinct. It’s not anything to be afraid of.) Third, it may be that Scorpio Rising people are not at all interested in the office of U.S. President. In fact, they do not like to be put on display. They prefer to wield low-key, subliminal power. To see the zero-count for Scorpio rising, see the graph “Rising Signs of U.S. Presidents”, shown above.
Her Scorpio Sun is better placed in the graph, but Virgo mid-heaven isn't doing too well.
As for "The Donald" - his Leo Sun (Fire) could be his undoing (one factor among many I dare say!) Final paragraph of the linked piece begins: "Earth, water, and air signs are pretty well represented in all three tallies. This favors a combination of dependable earth, compassionate water, and witty, airy intelligence. Fire signs ranked lowest among all three tallies."
