Positives1.) I noticed Ryan looking around the room and into the crowd a lot more often than I did during the first debate; which increases his own connection with the audience and really helps forge a stronger connection with the people listening.
2.) Ryan also addressed his 'indoor voice' issue during the debate; and while he continues to speak in a mild-mannered way (and as noted before, it's a strength for him and would perturb people if it changed) he did a much better job at emphasizing key words and points during this debate.
3.) Ryan found himself the subject of all the questions by the other candidates in the first questions round; and I thought he handled himself very well and was able to effectively address the concerns that were put forward; with one possible exception...
Negatives1.) That exception being his answer to Cam's question about remaining involved in the party if he doesn't win the leadership and whether or not he would seek a seat in the legislature. I think there's a lot riding on this particular question, and Ryan's answer was both affirming but also non-committal at the same time. I don't think you can say that you would provided you were welcomed in, which suggests that there's concern you wouldn't be; then turn around and say that no one on the stage seemed like they would exclude you. It seemed like a non-answer, and I think, it doesn't quite defuse the worry of Ryan dropping out of the limelight if he doesn't become leader.
2.) From the sounds of it, though I could be wrong, it sounded as though Ryan completely reused his closing statement from Regina (though in fairness, he wasn't the only candidate to do so.) I think over the course of fourteen debates, it's important for the candidates to use the time provided to them wisely. A reusing a closing statement seems like a wasted opportunity to add to the debate.
