There's one question, in particular, though, that I'd be keen to hear CoffeeHousers' views on: how much should Cameron and Clegg use Brown's gaffe against him? My thinking is that they've played it well so far - only offering limited comment along the lines of "I think the words speak for themselves" - and that they should continue the same approach tonight. If they say anything more direct, if they politicise the situation ahead of talking about the economy, then they risk triggering the (slight) possibility of a sympathy backlash in the PM's favour. This is one Brown disaster where they're better off keeping more or less schtum - and letting him stew in it.
P.S. Brown's meet 'n' greet problems clearly aren't behind him. He said to a factory worker this morning: "Your company's doing well in China." The worker replied: "Our company's doing well everywhere but I think it's in spite of you." Another classic for the Election 2010 scrapbook.
