From Modern Vedic Astrology:
On the heels of Barack Obama's successful world tour, his campaign has generated more potentially damaging controversy in recent days with the accusations about him playing the race card, the new McCain celeb ad that attempts to depict him in an unflattering light, and now Obama's apparent flip-flop on offshore drilling. Clearly, he is suffering the effects of the transiting Mars to his natal Mars. Several months ago, I had predicted that the first week of August would be a stressful and conflictual time for Obama and that seems to be taking place.
Given that Mars (25 Leo) is currently still a few degrees away from Obama's natal Mars (29 Leo), it's very likely that the upcoming week will mean more headaches and missteps for him. Remember, too, that the effect of this Mars transit to Obama is greatly magnified by the presence of transiting Uranus exactly opposite at 28 Aquarius. This combination can be volatile and is often associated with accidents and sudden actions which cause hardship. I don't think he's in any great danger here, but he's is likely to be on the receiving end of anger and animosity and maybe a rotten egg or tomato. I would expect more protests of the sort that he encountered in Florida when a number of black supporters tried to interrupted his speech. I think it's also possible that polling numbers to perhaps begin to favour McCain next week. Up to now, Obama has been ahead although his lead has shown signs of diminishing in recent weeks Obama's birthday is tomorrow August 4th. Before he blows out the candles, he may be wishing for Mars to get on its merry way.
I will post something on John McCain in the upcoming week. His natal Venus (29 Leo) will be subject to the same Mars-Uranus influence this week so he, too, may have to react to some sudden development that embodies some element of conflict or violence. It's possible there may be some news involving Iran that affects the presidential campaign.
