It's not bad. It's just not a debate, and bears no resemblance to Lincoln-Douglas. That label is a farce.
I'd like to see real debate of issues. You can have debate without "gotcha", no matter what Newt says.
They should do it like playoffs:
Paul v Cain
Romney v Newt
Have some mechanism for viewers to vote the winners.
Then a final between the winners.
Actually, it was a debate, and not an argument, which is a loose interpretation of the word “debate”:
de·bate (d-bt)
v. de·bat·ed, de·bat·ing, de·bates
v.intr.
1. To consider something; deliberate.
Now, if you mean you’d like to see more of where they disagree, well, that may be worthwhile. However, I personally loved the debate (not “bickering”) format, because they actually were able to address issues, although I don’t agree with many of their ideas, I do, however, believe that Cain, and to a lesser degree, Gingrich, both want to do what is best for our country (even if they aren’t sure what it is yet), or at least improve it.
