I saw the claims, but I didn't give them any credence. After all, similar claims had been made about Barry Goldwater (because he was born in Arizona before it was a state) and John McCain (because he was born in a U.S. military hospital in the Panama Canal Zone). I figured it was unlikely there was anything to the claims that Barack Obama was not a natural born citizen, and ineligible to run for president especially since there was an image of a Certificate of Live Birth posted on the Obama campaign web site.
But then it turned out there were at least two different Certificate versions out there, apparently both from the Obama campaign. That meant at least one had to be a forgery. Because of that, there began to be demands that Obama authorize the release of official documents to prove his eligibility. When Obama refused, lawsuits started getting filed in state and federal courts to force the documents' release and they weren't getting immediately dismissed. And Obama continues to fight those lawsuits, fighting to avoid the release of his birth records even interrupting his campaign to appear in court in Hawaii last week as part of this effort. (While there, he also visited his grandmother, who was released from the hospital a couple of weeks ago.)
When John McCain's eligibility was questioned because of his birth outside the (at the time) 48 states (in the Panama Canal Zone), his immediate response was to release the documents that demonstrated the falsity of the accusations. That's a complete contrast to Obama's response. Why? It's not like this is taking up any time from McCain's staff -- they've ignored this from the beginning. It's only taking up time and effort from Obama's staff and the DNC staff. Obama could end this any time by allowing the release of the documents. Why doesn't he?
I'm still trying to figure out what Obama is hiding here. I can only think it must be something that's really important to him, or he wouldn't be spending so much time & effort & money to keep it hidden. And I don't see that any legitimate purpose is served by Obama acting like a dirty Chicago machine politician. (Yes, I know that statement is repetitive and redundant.)
