Why Is Winston Digging A Deeper Hole?

Winston's personal statement in Parliament explained nothing and disappointed everyone. And it made the media even more angry. Why would he be so silly?

• could Winston see all this attention pushing him past the 5% threshold;
• could Winston's fans fall for his media conspiracy theory?
• or is Winston being careful because he doesn't know what is going to come out tomorrow? or the next day?
• or is he just a short arse ego maniac who gets off on all the publicity?
