I don't think DD, sporting a new tie, turned in a good performance but he remained dignified as he resisted JP's attempts to cover him with the usual effluent.
The questioning on the difference between a promise and a strategy and a guarantee was tortuous. And although DD committed no howler he couldn't keep still. His body language was very defensive. He perspired quite a bit. He was clearly uncomfortable with the tirade of insults that JP threw at him at the beginning of the interview. Insults like 'shit of the year' said to come from his Conservative parliamentary colleagues were greeted with a slightly hurt expression.
Tonight won't have helped Mr Davis although many viewers and voters will have felt some sympathy for him and dislike for Jeremy Paxman and his sneering style. Those interviews aren't designed for enlightenment but to showcase Paxman. The 'interviewer is star' is a bit like most 8.10am Today programme interviews. The interviews are blood sports - not a search for truth.
DC's decision to delay until next Thursday looks wiser tonight. 10% or so more voters will have cast their ballots by this time next week. DC can't be looking forward to JP's questions about his past etc. It was grim tonight; it could be grimmer next week...
