Trump can be well-defined, primarily, by two features in his birth-chart:

1. His Lunar Eclipse (bracketing everything else in his chart, to the eastern side)
2. His Leo+Mars Ascendant.

Elon’s chart intersects both of these.

1. Elon’s Venus very closely conjoins Trump’s lunar eclipse (only about 1° of distance)
2. Elon’s Mars is opposite Trump’s (6° distance)

Further, Since Elon’s Mars is conjoined (5°) Rāhu, it gives both men tight a Rahu+Masculine-Planet conjunction.

Also, the two can be said to benefit each other, since:

1. Trump’s Jupiter trines (2-3°) Elon’s Rāhu+Mars conjunction
2. Elon’s Jupiter trines (2-4°) Trump’s Saturn+Venus rājayoga.
