Right - he could have also “overcorrected” to confront Biden which would have been a risk of making it look like a school boy arguing with the school master (sort of the way Edwards looked vs. Cheney). In this case he looked like someone level headed with someone going crazy.
I agree. There was a danger of that, and he did come off level-headed. There’s also a very fine line there too, level headed vs submissive and not self-defending enough.
