As per Vedic astrology Barack Obama is all set to become the president of the United States of America for the second time in succession.
Born on 4th Aug 1961 at 19.24 in Honolulu, USA; he is running the main period of Saturn, sub-period of Saturn, sub-sub period of Saturn & sub-sub-sub period of Moon.
He is ruled by Saturn with Capricorn Ascendant & Saturn is exalted in transit... Moon too is exalted in the horoscope as 7th lord, the house of masses & public image; placed in 5th
House, the house of recognition.
He has completed his 51st year which should bring good luck as his ruler has become exalted after 27.5 years.
As per Gemini sutras, the transit of Jupiter (moving over his natal moon) promises big opportunity, status, recognition and power.
His last 2.5 years were full of stress & controversies because of Jupiter-Rahu dasha.
Though he is facing a tough challenge from his opponent Mitt Romney, I think because of Barack's Jupiter-Saturn combination on the Ascendent he will be blessed with good fortune.
May the best man win.
