It is close to impossible to predict accurately for public persons, whose birth times, and sometimes even dates, are generally unknown or incorrect. Nevertheless, predicting for them is challenging and rewarding in publicity, and hundreds of astrologers keep testing various times for the same charts, discussing each other’s opinions (although the only proof of the correctness of the data is the prediction that comes true).
The most discussed public figures at the moment are, indeed, US presidential candidates. In the recent UAC08, there was an announcement, which was considered as rather reliable, about Barack Obama’s birth in Honolulu on August 4, 1961, at 19:11.
I emailed Sri K.N.Rao asking his opinion about the chart for this time, because I had lots of doubts regarding the Jyotish chart for 19:11, where in three major vargas (rasi, navamsa and dasamsa) rulers of 10th houses were placed in 6th, hardly promising the high elevation Obama has already achieved.
Sri K.N.Rao generously shared his estimate of the time, pointing at 13:06. As I understand it, it was a result of his thorough rectification, and thus I felt confident to look at the chart for forecast.
The chart is very strong, with multiple Rajayogas, exalted ruler of 10th, Amatyakaraka in 10th house and Atmakaraka in fruitful 11th house, with powerful Rahu. 10th house is very energised by aspects of four planets.
In his present Vimsottari mahadasa of Jupiter (ruler of 10th house in dasamsa), from August 2008 to May 2009 Obama will be running antardasa of Sun (AmK in 10th in rasi) - this gives him a real chance. Yet, in dasamsa his 10th is on the Rahu-Ketu axis, and most Jaimini yogas disappear, except AmK-DK - and that's with Rahu.
Note that after antardasa of Sun, there comes antardasa of Moon (2009-2010), which is aspected by Jaimini rajayoga of Amk-DK. His wife’s involvement in his campaign is well-known (DK aspecting 10th in dasamsa), and this influence can become more pronounced in the next antardasa – with influence of Nodes. But this is later.
In Chara Dasa, at the time of November elections he will be running Virgo-Scorpio-Aries pratyantardasa (and on the day of the elections, time 13:06 promises Cancer and Leo sookshma-antardasas, which is really impressive: these are again 10th and 11th houses with AK and AmK). From Virgo, AmK Sun in placed in 11th; from Scorpio, AK is placed in 10th. In dasamsa, Virgo-Scorpio-Aries contain all four AmK, AK, PK and DK, and houses are 4th, 6th and 12th. This looks as a troublesome but rewarding period. This is the time to achieve.
The ruler of dasamsa 10th house Jupiter is retro in 6th under double aspect of malefics, Mars from 12th and Saturn from 4th. In fact, this and the ruler of dasamsa ascendent Mercury in 12th aspected by Jupiter, retro Saturn and Mars explain some of the career events in his past.
If Obama becomes president in November, 13:06 is the correct time of his birth.
Yet another problem is that several times may describe the native similarly well, taking into account all the life events etc.
Good exercise. Although I am not sure about his presidency now.
Update of 06.05.2011. The recently published Obama's certificate seems to be not genuine, which is explained in the following video (four parts).
