Here In-Depth analyses by Ema Kurent:
It would seem that with the imminent ingress of Jupiter into Gemini (June 12, 2012) the scales will soon tip to the Romney’s end. It’s not just Jupiter entering the 1st house of a natal chart, it’s ticking off all those powerful eclipse and nodal degrees. Jupiter will be transiting Romney’s 1st house right until the electional date, giving him a strong boost. We should also bear in mind that all this powerful stuff »sits« in Obama’s 4th house, and could ask ourselves a simple question: which house is stronger, the 1st or the 4th? Or: what brings us more success, more resources and more fame? The 4th house is not just the house of the family and the homeland, it’s also the house of beginnings and endings. The feeling that Romney could become Obama’s »end« cannot escape me.
In the meantime, Venus, Romney’s 10th house planet, which is now retrograde, will turn direct at the end of June, getting him more support. Soon afterwards (July), transiting Uranus will close on its sextile to Venus – a powerful aspect due to Uranus' corulership of his MC (Aquarius). In the second half of July and around September 10 there could be some mischief, due to the progressed Moon’s inconjunctions to his Neptune (progressed and natal), but there follows a trine with Pluto, reinforcing his progressed MC trine with the same planet (exact in the following months), which should be all the more helpful.
Obama? In June 2012, his progressed ascendant will square his natal Saturn which is his chart ruler (ascendant Aquarius), which shows obstruction. Moon will trine his natal Sun in August, which is helpful, of course, but due to all the support that Romney will obviously be getting in that period, it may just not be enough. On the other hand, Moon will transit Obama’s Sun on the day of the elections, giving him much public support – meaning votes, of course! His (precessed) lunar return for the month of the election is also favorable.
If someone asked me who I think will be the next president of the United States, I’d say that Mitt Romney is a very strong rival and could get ahead of Obama soon (I write this article in the first days of June 2012), and that I wouldn’t be surprised if he won the election.
Still, this is not a straight prediction!
