On the whole, I don't know if this will change much.
She started much better than he I think.
On money in politics, Hillary is still bad. She should really just be upfront and say, yes, I'll take it because without it we're going to get crushed by Koch money.
On FP, Sanders has studied up but it was a history textbook rather than a look at modern threats - it still looks like he's more interested in bring up the past rather than putting together what he plans to change, and it stood out actually a bit more in some of the things he brought up. So better, not great.
I'm not entirely sure how the ending will play. I think it could have been a good pivot, but I don't know if she took it too far.
Throughout the debate, Sanders repeatedly looked highly flustered in split screens. It's something that probably should be worked on.
Also burning hate of a thousand suns for each other, like lasers from their eyes.
