Cameron seemed to be out of the debate, letting the other two say what they wanted to say. He was good at the set piece questions, but not at butting in. Ability score: dull wallpaper
Brown oozed practised relaxation, and the happy pills were obviously working, as he seemed to be relaxed an enjoying himself. Deadly earnest (zzzzzzz), well informed and impeccably well read on the policy issues (zzzzzzz in spades). Public interest score: personality-free accountant
Clegg grew in stature from a low standing start some two weeks ago and appeared to be the most confident of the three. Perhaps not so sure about the impact of his policies, but was able to put the knife in where it told. The target of the other parties, he found himself in the unexpected position of appearing to be doing well. Electability score: nice guy in the pub who you think should stand as Councillor, but might not actually vote for.
The winner? Anyone who didn't watch this version of PMQ with the prepared answers to prepared questions.
Roll on debate 3.
