Since we posted on the Leaders’ Debate Poll conducted by YouGov on Thursday there has been an extraordinary revelation.  YouGov says their internet poll on the TV debate was conducted between 9.27pm and 9.31pm, so the majority of responses were taken during the debate not after it.

This is critical because it means the poll was taken during the summing up speeches.  The speeches took place at the following times:

Brown          9:26:30  – 9:28:05

Cameron     9:28:08  – 9:29:17

Clegg            9:29:18  – 9:30:47‬

That means that over half of the polling would have been done before Clegg summed up in the debate.   It also meant that up to half the responses were taken whilst Cameron was summing up and had sole command of the floor and the cameras.  That’s a serious flaw in the process and is either incompetence or intentional distortion.  You decide which you think it was.
