welcome to debate #2, night 2. with night one out of the way, and the expectations set by our first night of candidates, we turn to a much more diverse, much more ideologically separated group of candidates ranging from asian-american technocrat andrew yang to moderate-progressives african-americans in booker and harris, and from berniecrat-type tulsi gabbard to solidly moderate joe biden. it seems likely that we'll see more fireworks today than we did last night, especially given CNN's adversarial lines of questioning in the first night. as always, here are all the details you'd ever need, and probably then some:

i recommend you sort by newest first (or order posted) instead of the default since this thread will likely be semi-active and covering a live event.

The Rules:

A candidate "who consistently interrupts" on Tuesday and Wednesday nights will be penalized by having his or her time reduced.
Campaign representatives have also been told there will be no "lightning round"-type questions requiring a show of hands or one word responses.
The debate will be moderated by Dana Bash, Don Lemon and Jake Tapper. Each of the 10 candidates each night will be allowed to make brief opening and closing statements, the network said.

The Analysis:

NPR has 5 questions for this debate:

1. Will there be any distinctions drawn between Sanders and Warren?
2. Will some of the air be taken out of Sanders' sails because Biden isn't onstage?
3. How is race raised?
4. Who breaks out?
5. Without hand-raising, will we get answers that are as clear?
