In a lot of ways, I think O'Rourke had a better night than Harris. Admittedly, the bar was probably lower for him, since he hasn't yet had a moment and has been struggling in the polls for several months now. But O'Rourke seemed much more energetic than he did in the past two debates, and more focused. He could talk emotionally about the shooting in El Paso because it took place in his hometown, and he came through on that. On the other hand, it does seem like the other candidates don't see him as a threat — the front-runners were not being congratulated for how they handled something recently.
Harris, on the other hand, was mostly fine but kind of inconsistent. She seemed to get a little lost during a few answers. And she certainly didn't manage to say anything as incisive or attention-getting as her attack on Biden during the first debate. Tonight is likely not going to help her improve her standing in the polls.
