In reply to pec:
Seriously question that GB staged that one, though he maybe does get sick of statements/questions that begin with "I'm not a racist, but....", and decided to see how robustly he could get away with challenging them.
Doubt anybody would question that DC and his motley crew of Conservatives and conservatives would have loved to have been free to play the royalist card more explicitly and earlier in the campaign. And while probably not staged in terms of positioning the mike, I'd be very suspicious that he saw a good "shot to nothing"; chuck it out there, if it's picked up great, if not nothing lost.
GrahamD suggests that shows him to be a "good politician"; in the sense of a sleazy, manipulative git that's good at politics then yes...but that's exactly what most of those of us that voted Yes wanted rid off
