Romney's campaign team is doing just what it needs to. They are fine.
Obama's campaign team is lost. It is trying to play Romney into a corner and paint him as a 'birther' or if not...weak-willed to stand up to any of his supporters large or small who speaks out on the frail argument Obama is tottering and tilting on regarding all his past.
Giving more airtime, public thoughts, and investigation regarding info about all Obama's records, especially his foreign student status, will eventually damage his efforts more. There are no more October surprises from his campaign, everything is predictable and based off timetables of political survival. That strategy is easily defeatable.
