Whatever may be on Obama's COLB, it is hard for me to have any sympathy for someone who colluded with the press to have has opponent's sealed divorce records made public, as Obama did in his US Senate race.
The more I see of Obama, the more I think he's an arrogant snob, who gives himself props for "slumming it" as a community organizer and who thinks he is above the rules set up for us commoners.
That's the only "3rd explanation." Maybe he isn't actually the son of Barack Obama sr. or something like that which would make his biography kind of stupid.
