From Modern Vedic Astrology
I believe that Obama and the Democrats will once again move into the lead in the polls by early October.
But at that point, Obama's campaign will stumble, perhaps fatally, on or around October 15-16 as Mercury stations on the 6th house of the campaign chart at the same time that Mars conjoins the descendant. This is really a very negative pattern that speaks to conflict, misunderstandings, and stress. Since this occurs near the time of the last debate on foreign policy, it may reflect a poor performance by Obama. Since this is the last debate, a bad showing there could be difficult to come back from. Obama will have to be in the lead before this debate in order to have any chance of winning on election day. He is almost certain to lose some popularity as a result of events of Oct. 15th. If he goes on to win, it likely won't be by a wide margin.
The exact Saturn-Uranus opposition on election day promises an election unlike any other. We already know it will be historically significant in some way depending on if Obama or Palin are elected. But I think the extent of the energy and tension of that day will exceed the symbolic nature of the outcome. It promises to be one very wild ride.
