The mudslinging was a total turn-off. Richardson tried to call the others out on it but ended up joining in later on.
It was interesting to see Richardson try to pass off a carbon cap-and-trade system as being less costly for consumers than a carbon tax... I was glad Obama called him out on it. We need leaders willing to publicly state the reality that reducing carbon output by any method will require some sacrifice. That is the only way to get the public to accept it and move forward constructively.
In the end, I thought Edwards came out of the debate looking the best due to his passionate speech against special interests. It's unclear though what exactly he would do to contain them once he got to the White House. I think I like all of the candidates a little more now than I did before watching the debate, especially Hillary.
