There are a couple of reasons why it is difficult to accurate charts for the inauguration, Salem.
First, we really do not know Obama's birth date and time. There are a lot of lawsuits demanding that he give his "long-form" birth certificate, signed by an attending physician, showing hospital location, time, parentage, etc. He supposedly has spent quite a lot of money on lawyers trying to stop these suits.
The second reason is that there is also some speculation that he will actually be sworn in at a private ceremony at a different time. Whether any of this is true or not, I have no idea. You know how difficult is is to be sure of stuff that is going around the internet.
One thing that really bothers me is the position of Obama's Neptune, not only in relation to the swearing in ceremony, but also in his own chart, and to the US natal chart.
Obama, if his birthdate is correct, has Sun square Neptune. His natal Mars is exactly conjunct the US Neptune. And, on Inauguration Day, transiting Saturn is conjunct Obama's natal Mars.
And, if you remember, we are enjoying a nice long recurring Saturn/Uranus opposition.
Now, the keywords for the planets involved are as in mundane astrology is as follows:
Neptune
- rules socialism, communism and left-wing political ideas (its urge is towards collectivism). It is linked with mobs, secret plots, sedition, fraud and swindling, all illicit undertakings, bogus companies, loss and vice.
The Sun
- represents the Prime Minister, President, Head of State, monarch, aristocracy, magistrates, judges and all persons in authority and of distinction, Cabinet ministers and the like. It also represents public heroes and national champions.
Mars
- governs the military, soldiers and noted military and naval men. War, terrorist attacks, industrial disputes, strikes and conflicts. Opposition forces. Fire, fire services, arson and incendiarism.
Saturn
- has chief influence over elderly people and governs the national death rate. Life-threatening epidemics. Land-owners, farmers, mines, coal and industries connected to metals and minerals. State funerals, public sorrow and dissapointment.
Now, about the Inauguration Chart itself...
First off, the Moon is void-of course. Traditionally things that happen under a Void of course moon do not work out well, or come to fruition, and this moon is at the last degree of Scorpio, unpleasant position actually!
Next, Mercury will be retrograde. Not a good situation for undertaking new projects! My guess is that Obama's administration is going to disappoint a lot of people, and he will face a lot of challenges and hostility.
We will have to wait and see how things turn out for our nation. I am worried. Most astrologers are very liberal, I find, and would not worry about Obama's impact on our nation as I do, just so you know.
