What flim flam? Expected to give a full costed policy on a question time panel - never in the history of a panel political programme has that ever happened, and it has never, ever happened in a campaign period.
It was a well coped with QT - nothing broken, lines held to, policies defended against the reality of what will happen one one if Labour get into power, nothing to hold them to with over promises if they get into power. You have to ram home the message again and again and again before it goes in - which is why you'll hear change, change, change and change again over and over and over again. Also Stability is Change seems to keep cropping up from Labour HQ - they have to balance being favourites and being humble - to promise more but also ensure they are not hung out to dry by their words in the first 100 days. Its a real balancing act.
I really think you might want to do a bit more finding out first. Although, I have to remind myself that the majority of the country are voting from this position, so yes that's why you'll hear soundbites because ultimatley this is what works.
