Bill Hemmer and his 'undecided group'?
They had this little gadgets with buttons on them that should measure viwer's emotions during the debate.
Hemmer said (and showed) the 2 biggest spikes was when Cheney spoke about gay marriage and when Edwards spoke about outsourcing. The average spike was about 2 points on these.
However what he didn't say is why Cheney's line was at 5 (jumped to 7) and Edwards's was at 7 (jumped to 9).
It will be interesting to see these lines for the whole debate. I suspect Edwards's performance rated at 6-7 on average for the whole of the debate, while Cheney's was at the middle of the scale.
