You are right, but the effort as I understood it was to obtain this information in time for it to be presented to the electorate BEFORE the election.
I get the feeling that Obama is trying to run out the clock. Presuming that he is hiding something, he probably figures that he will be negotiating from a much stronger position if he wins the election.
However, I expect this issue will not go away if he wins the election. The problem is that the court system will continue to stone-wall, claiming that no single person has standing to challenge his eligibility.
It's probably going to come down to when the true election (the meeting of the electors) is held. At that time, perhaps one of the electors representing McCain will make the challenge. And that will create turmoil that will make the 2000 election look tame.
The Supreme Court will have to decide what a natural-born citizen is, and take Obama's history of citizenship (US, Kenyan, Indonesian) into account. And it will probably come down to a 5-4 vote, with Stevens casting the deciding vote. Either outcome will fracture this nation, possibly the worst since the Civil War. Nobody wins, everyone loses.
The easiest way to avoid this possible outcome is for McCain to win.
