While I think Obama is hiding something and that the long-form BC is clearly a computer-generated document and not a scan of a piece of paper - I also agree with your conclusion. Whether you view it as the last word, or just another clever Obama head-fake, the BC issue is resolved in the minds of most Americans and it is not an argument that can help us win control of the White House in 2012.
Like many, I’ll probably continue to fuss about it, but what I think matters not. Candidates and opinion-shapers need to stay focused on the real issues and attacking Obama’s policies, not his citizenship.
Completely abandoning the issue would be a mistake. IMHO. The questions surrounding eligibility and curious COLB add weight to all other more easily defined reasons to dump the chump.
