I don't know if anyone here subscribes to the free Zyntara newsletter, (B. Brady & Darrlyn Gunzburg)
but their latest Visual Astrology is all about the upcoming election, and its quite a fascinating read.
Bottom line is they do not know either, which candidate (Obama or McCain), will take it, but it does appear they have put a lot of work into statistical data, between the parties, (Democrats vs Republicans) over the past few hundred years to compile a lot of info......and found that every 8 years Venus returns to it's original place in the zodiac, and the U.S. Elections are timing (unintentionally) to this Venus return.
 
Thus, this November 4th, is what they say will be a Venus Evening Star Election.
 
Venus is either a Morning star or an Evening star, during this cycle, the Morning star of Venus
being in the early degrees of Libra and the evening star would be in the middle degrees of Sagittarius.
 
 
But who does it favor, is not too easy to answer although as I said the article takes you through the prism of the constellations in the skies, as though you were back during the Mesopotamian Astrologer/Priests eyes...seeing then the constellations at work that day, in each of the candidates and how the sky will either "favor" through the rays of Venus to the nearest planet, OR "not favor".....the sitting family (they use the analogy of the king and the rival to the throne.)
 
In this case the Rival to the throne would be Barack Obama, and hopefully, Venus will cast it's ray's upon Jupiter which will be on the ecliptic, but not as close as Pluto to Venus, hence, Pluto may emerge the victor once again. (as in 2000 and 2004) or Republican.
 
I'm cheering on for Jupiter playing a major role in this change of kingship , retiring king or not, the "family" of the king is still Republican family i.e. J. McCain.
 
You really need to sign up for the newsletter or look for the archived article, once it is archived in a month or two. Meanwhile, I don't think they would mind my posting an "excerpt" from their excellent work:

The 2008 Evening Star Election
At the time of the election Venus is once again radiating Pluto but differently to the 2000 election as there is also a distant but bright Jupiter in the cape of Sagittarius (see image above). If Venus�?empowerment goes to both planets, questionable as the orbs are wide, then this would symbolise a landslide victory to the younger "crown prince", a bold sweeping ascent to the White House where the sheer weight of the mandate places great power in the hands of Obama. Such power can be a heady drug for any politician so the younger rival will need to remember that he is not Caesar, he is not one of the gods and is only human.  
 
 
But if Venus' light does not reach Jupiter, then the emphasis will be focused on the raw power-struggle of Pluto. The election will be won by the "family" with the most money, power and grit. Adding to this intrigue, the heir of the retiring king is not being damaged by Mars. Rather that Mars is expressing itself as John McCain, the Soldier.  
 
One gets a sense already of the power of the Jupiter Pluto victory to the young contender, Obama, but if it comes to a fist fight in the manner of the 2000 election - the last Evening Star election where Venus radiated Pluto  - then the victory will go to the one who can wield the most money and power.  
 
The victory will be most sweet for it will last for twelve years
 
On a final note, whichever party gains the White House, they will hold it not only in the 2012 elections but also in the 2016 elections. In the election of 2012 a Morning Star Venus radiates the Sun-Saturn conjunction which will give much blessing on the king. In the 2016 which is an Evening Star election, Venus once again radiates Saturn, with no threat to the king. So Visual Astrology is indicating that the ruling party will hold the White House for at least 12 years. Presidents may change at any stage but the "family" that wins this current election in 2008 gets a very large prize indeed.  
 
 
Kings or Presidents, it is all just power and rivals which is the intrigue of any royal court. Not much has really changed since astrology first emerged between the rivers of the fertile crescent.
