I know I keep flogging these debate data….but I just can’t help myself! Democracy Corps did pre-post debate surveys for each debate, which have all been released, including the last one. But, as Paul Waldman points out at the Gadflyer:
…instead of looking at the differences from Wednesday to Thursday, we should look at how far the candidates have come since before all the debates began.
The DCorps data allow us to do that–compare pre-first debate to post-third debate–and here’s what the data say, according to Waldman:
…people’s opinions of Bush after the debates are just where they were before the debates, while Kerry has improved dramatically on every measure. Bush’s average improvement was one-half of a percentage point, while Kerry’s average improvement was 9.5%.
Waldman goes on to give the changes for Kerry on each individual candidate attribute, as well as the changes for Bush. It’s quite eye-opening. See the link above for all the data. (Note: I am told that DCorps will be releasing charts summarizing these changes and others over the course of the debates very shortly. I will provide a link to these charts when they are posted.)
