Since the guy has never produced evidence that he is American, I am not sure how this can be compared to rabid BDS. This is a reasonable issue that should have been dealt with by the courts before the election. If somehow this came to light now after the election all hell will break loose.

Since the Clinton era I have found it useful on many occasions to ask “What is the innocent explanation?” In this case Obama could have stopped the conspiracists in their tracks by just releasing a copy of his birth certificate. Same for Kerrey’s 527, Clinton’s State Department records and Sandy Burglar’s stolen papers. At least there is an innocent explanation for Obama’s trip to Hawaii, believe it or not.
