Personally, I've always thought that whether he was born in Hawaii or not - and I had no real opinion on the subject - it would never be allowed to interfere with his holding the office. Too much chaos would result if he were proven to be ineligible. Worse, the Vice Plagiarist would then be the Plagiarist-in-Chief.
Still...why did he wait two and a half years to do something he could have easily done when he was running for President? By stonewalling, all he did was fan the flames. It's far too late for him to complain that it's soaked up too much of our national energy now, since it's his own fault for not releasing it sooner.
