Shades of John McCain’s political blunder in this Times piece:

So how many properties do you own? “I own a house in North Kensington which you’ve been to and my house in the constituency in Oxfordshire and that is, as far as I know, all I have.”

A house in Cornwall? “No, that is, Samantha used to have a timeshare in South Devon but she doesn’t any more.” And there isn’t a fourth? “I don’t think so – not that I can think of.” Please don’t say, “Not that I can think of.” “You might be… Samantha owns a field in Scunthorpe but she doesn’t own a house…”

The rest of the interview was punctuated with Cameron’s nagging anxiety about how this exchange was going to make him sound: “I was wondering how that will come across as a soundbite”; “‘Not that I can think of’ makes me sound… I am really worried about that…”; “I am still thinking about this house thing”; and his parting shot was: “Do not make me sound like a prat for not knowing how many houses I’ve got.”
