Josh Marshall over at TPM writes, "Hillary's Big, Big Night."

Highlights:
HRC had a very solid performance ... turned away questions on her vulnerabilities with confident and convincing pivots ... had the feel of a candidate on the rebound.
We were running Insight polls overnight and this morning, gauging reactions to the debate and re-testing Democratic primary preference questions we've been running for the last four months. Based on those results I would expect you'll see Hillary get a substantial boost in the polls coming out of night's first debate.
Also: Sanders "seemed strong throughout ... our numbers show that his already high favorability numbers actually went up significantly ... unfavorables, already low, plummeted."
Hillary's favorability numbers also went up, but not dramatically. Where you see the difference is on candidate preference where her support shot up a lot. (Italics mine)
She took some support from Sanders, but not much. Where she got most of her support was from people who'd been supporting Joe Biden ... and undecideds.
As I said, she did very well and expect this performance to drive her poll numbers a lot.
My view: Favorability is great. "I'm going to vote for that person" is much better.
