Didn't see PMQs today - I was having lunch with Dr Robert Shapiro, former economic adviser to Clinton, Gore and Kerry (the other one) and now an adviser to the Obama transition team. By all accounts it was a massacre (PMQs, not lunch). Cameron is caught in a difficult position; he can't re-establish his credibility unless he talks about the economy. And he can't re-establish his credibility if he does - because (a) the Conservatives are all over the place on it, (b) he doesn't know very much about it, and (c) Gordon does.
In response to a journalist's question at the seminar which followed lunch, Dr Shapiro described Gordon's response to the economic downturn as 'superb'. He then slightly spoilt it by adding 'especially when compared to George Bush and Henry Paulson'.
Speaking of Kerry (the other one), I was visiting a friend at the weekend and he was wearing the 'Scary Kerry' T-shirt I'd bought him in Washington at the time of the last election. Kind of wish I'd kept that for myself now.
