I personally think they've cocked up so badly now, it's a case of Rob as much as possible for their mates and lose the election. They can then wander off and let Labour or a Lab/Lib co team try and wade through what is left of the country.
They don't want to win next time. Because that would mean trying to sort out their own mess.
That way, when another election rolls around, and Labour haven't been able to come close to sorting things, they and the media will be all "see, Labour can't do anything, everything is a mess". And the same people who believed Boris' crap will fall for it again with another no doubt just as moronic twit
