Just for kicks, let's consider President Obama's natal Sun-Moon blend and his Secondary Progressed Sun-Moon blend for April 17, 2015 with the SP Moon remaining approximately 10 more months in the Venus-ruled sign of Taurus:
Assuming we accept its accuracy, the natal horoscope of Barack Obama (August 4, 1961 7:24 pm AHST Honolulu, Hawaii) shows a Sun Leo-Moon Gemini blend of Fire and Air, the "live wire" combo full of bluster and joie de vivre. In dramatic Leo we see a lion; in talkative Gemini is a teacher, orator, and a facile-tongued messenger whose rhetoric is lifted by the fire of his Leonine Mercury.
Sun Leo-Moon Gemini is a humorous, quick-witted, analytical, and resourceful blend of energies with high aspirations--the "thinking activist." Friendly, optimistic, and resilient, this blend can be emotionally fickle, restless, and rebellious like a child; there is a tendency to rationalize.
Sun Leo-Moon Gemini's 'Images for Integration' of the conscious mind (adult) and the unconscious (child) are: "Children singing 'Happy Birthday to you' at a celebrity birthday party...On a bright summer's day a butterfly turns into a radiant being."
Progressing the president's natal horoscope to April 17, 2015, we find his Sun has progressed from 12Leo32 to 4Lib33 and natal Moon from 3Gem21 to 20Tau46 which denotes that Barack Obama has evolved into a Sun Libra-Moon Taurus personality blend of Air and Earth. This describes the rationality of a 'practical idealist' who observes, plans, and takes action. Libra and Taurus are both ruled by Venus within her realms of evaluation, finance, growth (Taurus), beauty, art, partnership, and diplomacy (Libra) and denotes a time of cooperation, campaigning for the social good (except on Fast-Track authority to shove more so-called 'free trade' deals through Congress which will decimate US jobs, various protections, and America's sovereignty--and give Congress a free pass when they're campaigning again--aka, Global Government implementation). Also indicated by this Venusian blend are vanity and promoting the abstract theories of the upper class.
Sun Lib-Moon Taurus' "Images for Integration" are: "A lecture on ancient Greek architecture and town planning...Newlyweds go on a gourmet's tour of Italy for their honeymoon." (Sun Sign-Moon Sign, Charles and Suzi Harvey.)
The first Image reminds me of Masonic Washington DC architecture and its planning by America's early Freemasons and others--built using megalithic measurements as are Stonehenge and other ancient monuments (observatories) across the globe. The second Image reminds me a president's travel itinerary to foreign lands.
So there he is, morphed into a Sun Libra-Moon Taurus personality which will, in about 10 months, change into a Sun Libra-Moon Gemini personality with the SP (Secondary Progressed) Moon in about one year or so reaching his natal Moon position (3Gem21), a personal culmination of some sort, before he leaves office. This will result in a lazy double-Air Sun Libra-Moon Gemini blend that tends to skim the surface and spread itself too thin.
And in relation to Politics and the legal system, one of its Images is instructive, I think: "Having delivered a fair judgment, the chairman of a conciliation and arbitration board chats amiably with the previously opposing factions."
