Scorpio Joe Biden has been married to his Gemini wife, Jill, for 31 years as of last June, so for a couple with inconjunct Sun signs, they obviously have a lot going for them.
Fortunately, with good complete birth data for Joe, we have a chart wheel to work with. He has Sagittarius Rising, placing Gemini on the cusp of his seventh house, which rules marriage and committed relationships. Jill’s Sun, Mars, and Moon are located there. Planets in the seventh house in synastry, particularly the luminaries, show excellent compatibility in one-on-one relationships. Joe has Saturn conjunct Uranus conjunct his Descendant natally, describing the type of person he is attracted to. In his case, it’s a bright, lively Gemini who is also dependable.
Jill’s Sun-Mars conjunction is sextile Jupiter in Aries, giving her a more assertive edge and an optimistic spirit – both qualities she shares with her Scorpio Sun-Sagittarius Rising husband. Mercury is Gemini’s ruling planet, and her Mercury is in methodical Taurus and complements Joe’s Mercury in intense Scorpio. Another parallel between their charts is his Sun-Mercury conjunction, which resonates with her Gemini Sun.
They have a lovely Mercury-Venus intra-aspect, underlining their ability to communicate with thoughtfulness and sensitivity to the other’s feelings (intra-aspect in synastry is where the same two planets from each chart form aspects. For example, A’s Sun is conjunct B’s Moon and B’s Moon is square A’s Sun). This is a very loving and powerful synastry aspect. The close trine between her Venus in Cancer and his in Scorpio adds another layer of shared warmth and affection.
This couple also has what can be considered a classic synastry aspect for creating enduring bonds, and that is a Sun-Saturn intra-aspect with his Saturn conjunct her Sun and her Saturn sextile his Sun. With the Saturn-Sun conjunction located in his seventh house, their choosing to marry was a natural progression for the relationship.
Mars and Pluto, co-rulers of Joe’s four planets in Scorpio, form an intra-aspect between their charts, too. His Pluto in Leo is sextile her Mars in Gemini, and her Pluto in Leo squares his Scorpio Mars. Passion and commitment go hand in hand with this set of aspects.
They do have reversed lunar nodes, with his North Node in Virgo and her in Pisces. This can be a rather irritating aspect to live with day to day, but since they have been together for many years, I’m inclined to believe the other excellent synastry aspects offset the effects of this one.
As with the other political couples I’ve reviewed, this is yet another instance when it would be wonderful to have a full set of birth data for both people. However, working with what’s available shows us the underlying structure for the enduring and loving relationship we see before us. Seeing Joe and Jill Biden together says it all.

In honor of Mars entering his home sign of Scorpio, I selected this post on how Pluto in our natal charts affects our ability to relate to others.
With Sun signs in Virgo and Taurus, John and Cindy McCain are an earth duo. They share an appreciation for the here-and-now reality of the physical world and a generally conservative approach to life.
Barack and Michelle Obama, possibly the next president and first lady of the United States, bring great aspects for compatibility to their Leo-Capricorn relationship.
If there ever was a couple whose synastry was defined by the inconjunct (150°) aspect, this is it. These are two strong-minded individuals, he with the Sun, Moon, Pluto, and Uranus in Virgo, and she with the Sun, Mars, and Saturn tightly conjunct in Aquarius.
Since I’ve been coming across Neptune aspects in the compatibility charts I’ve been working with lately, this is the post I decided to pull from the archives. Neptune has also been a powerful influence in the sky lately too, conjuncting the Full Moon in Aquarius. It does not pay to ignore this subtle but powerful planet.
Many times we need to choose what the nature of a relationship will be. Will we be friends or lovers?
Neith’s response:
I got to thinking about why we are drawn to certain people whether we met them face-to-face or online and it has a lot to do with having planets and Angles within a few degrees of each other. As an astrologer I have consistently noted my clients have planets sharing degrees with those in my chart and I just read in John Townley’s book, The Composite Chart, he and other astrologers have a similar experience.
