Obama 'released' his jpg on June 12, 2008, after Hillary conceded the primary race. The things that led to the biggest doubts about the legitimacy of Obama's COLB didn't come out until AFTER the window of opportunity had passed.
I am sure there is at least one Republican election law lawyer in Hawaii who was and is familiar with the statutes, if for nothing else to make sure our candidate are properly submitted to the state.
I've followed this issue since June 2008 and I honestly can't recall anybody else talking about these kinds of statutes at the time. IIRC, one of the lawsuits filed in Hawaii was kicked out, partially because the court recognized this was one way Obama could have been challenged, but the lawsuit was filed too late to take advantage of the law. If Obama runs in 2012, he will be challenged. The bigger question is how the challenged will be handled.
