The Lib Dem surge shows Labour continuing to benefit in the Sunday polls. With figures like these, any one of the three parties can take the lead. But after years in the lead this is hardly the time for Conservative support to be exposed as soft. If this pattern is held the result will be unpredictable. Those hoping for another game changer from the next Leaders Debate may be disappointed. First because a repeat of the first debates impact is far from guaranteed and second, the debate is live only on Sky News, a digital channel of course, where its regular weekly share of the TV audience is 0.6% compared to BBC1s 20% although theres a repeat in 11.30 pm graveyard slot on BBC2. In view of the first debates high impact, the lateral thought for the second would be to simulcast it on the obvious terrestrial channel C 4, but I daresay that wont happen.
