Did Osborne Fail to Nail the Budget on Today?

Spectator editor Fraser Nelson thinks he failed. He points out in his online post that Osborne failed to lift himself up from overly technical language, whereas his predecessors - especially Ken Clarke - would use everyday language to make their points; he was also stymied by being interviewed by Evan Davis, who knows his beans when it comes to economics and managed to show up the paucity of Osborne's promises. Nelson's main point, however, seems to be that Osborne failed in presentational terms, not that he doesn't know his stuff or doesn't have a good case. Much has been made in recent weeks, of course, of the apparent Tory strategy of keeping Osborne out of the public side of the campaign - could this be why?
