While true, and with the caveat that the office has only existed since 2008, I believe this is the only time we haven't had a PBO. The other appointments were either permanent or one temporary, and picked up immediately after the other. Not having one appointed is nothing short of a deliberate decision to not have one, either because they don't care to have one, or they're probably trying real hard to find someone both acceptable to everyone yet the least likely to cause them headaches (purely guessing on my part of course). It's not like we weren't all fully aware that the term would end and a new PBO would have to be appointed.
