There's no way in hell that British Obama will ever gain any foothold on British politics here again. He is one of the most despised parasites in the country.
Everyone here knows he's a war criminal and everyone knows that he fixed the law so that he couldn't be prosecuted for his crimes.
That said, the only way he'll ever get back into mainstream politics is if he cheated and given that he has so many skeletons in his closet, that wouldn't surprise me.
Interesting timing though considering what's going on in the US.. Perhaps he feels the urgent need to ensure secret stay secret.
