All five have different Sun signs, but the astrology gets more interesting …
JCD — Aries Sun
Dolly — Capricorn
Trump — Gemini
Bush — Cancer
Clinton — Leo
Then Tesla: Cancer Sun, but Jupiter at 8.6° Aries.
Djokovic: Gemini Sun, but North Node at about 9° Aries.
So JCD is the only one whose Sun itself is Aries, while Tesla and Djokovic both have striking Aries placements…..
