I've been following this story since it's early days on the website that originally did the analysis/research at http://texasdarlin.wordpress.com/. After bloggers on this website (which is, by the way, started by a democrat) began to wonder why all the stalling in showing his birth certificate, they were very skeptical when he finally posted the certificate of live birth on the Daily Kos website and his fight-the-smears website. The investigative blogger (Texasdarlin) and several other smart bloggers did an amazing job researching the legitimacy of the birth certificate and researching the sequence of events in Obama's life--much of which came from his own writings as well as other interviews and articles. They concluded that the certificate of live birth (which is not a birth certificate--no one has ever seen a copy of his full length birth certificate) is a forgery.
They then used deductive reasoning to conclude that either he is hiding the fact that he was, in fact, not born in the US OR that his current, legal birth certificate is, in fact, the one he got when he was adopted by his Indonesian step-father and therefore, his current legal name is Barry Soetoro. This would mean that he is probably still an Indonesian citizen and may not have ever gotten his US citizenship back. Berg picked up on all the blogs they had written to support their argument, which was impressive, and moved it into this lawsuit. If either assertion turns out to be true, then Obama will not be eligible to be president and we will have been witness to an amazing con of the American people. It is now becoming obvious that Obama has something to hide or else he would have done what John McCain did when his birth circumstances were questioned--bring out the full length birth certificate.
In addition, all this has brought to light the gaping hole in our national security that exists surrounding a presidential election. First of all, the FBI does NOT do background checks on sitting US Senators before giving them a security clearance. Although the constitution states the requirements of eligibility to be president, it is NO ONE's official duty to check to make sure the candidate, in fact, qualifies. It's all based on the candidate signing an affidavit declaring himself qualified. NO ONE checks up to see if they are lying! And once the election starts, no one wants to be the one to question the integrity of a candidate (even one from Chicago!) so everyone tiptoes around the issue.
If he is disqualified, it will come as a huge shock because the only way anyone will have heard of this is through the internet.
It has all been amazing to watch this unfold and realize that the mainstream media is SO in the tank for Obama that none of them would even report the lawsuit. Of course, documentation supporting this may be what the McCain campaign has been holding back as the rumored "October Surprise".
