Reading Tony Blair's analysis about why Labour lost the election, I was reminded of a piece of post-election analysis done by Greenberg Quinlan Rosner Research:

They asked, amongst other things, the following question:

"I'd like to rate your feelings toward some people and organisations, with one hundred meaning a VERY WARM, FAVOURABLE feeling; zero meaning a VERY COLD, UNFAVOURABLE feeling; and fifty meaning not particularly warm or cold. You can use any number from zero to one hundred, the higher the number the more favourable your feelings are toward that person or organisation. If you have no opinion or never heard of that person or organisation, please say so."

So more people who voted in the 2010 election had negative views of Tony Blair than of Gordon Brown, either Miliband brother, Ed Balls, the European Union, the Labour Party, immigration, Israel or Palestine.
