what would be good news for labour would be discovering that jim murphy is in fact a fantastic orator and has the scottish electorate eating out of his hand.
// The YouGov poll for the Sunday Times, taken after Thursday’s Channel 4/Sky TV grilling for the two party leaders by Jeremy Paxman put Labour on 36%, and the Conservatives on 32%. //
After the debate Labour have a 4 point lead. The last YouGov poll gave the Conservatives a 4 point lead.
Either the voters didn't think Cameron won, or Labour's lead would have been far greater if it wasn't for the debate.
