Analysis

A lot is on the line in the 2020 primary debate. It might be the last chance for moderates to slow Bernie Sanders' momentum. And who comes out better — Joe Biden or Michael Bloomberg? Here's a guide.

The Vermont senator won the most votes in Iowa. Now he's won New Hampshire and Nevada outright. That makes him the front-runner for the Democratic nomination.

Sen. Bernie Sanders is the favorite, but does Elizabeth Warren peel away some progressives after a fiery debate performance? Former Vice President Biden has a lot on the line — and a lot to prove.

It was former New York Mayor Michael Bloomberg's first debate after spending more than $300 million on ads. He had an uneven performance, especially when it came to his record on women.

The survey by NPR/PBS NewsHour/Marist gives the former New York mayor enough polls showing him over 10% nationally to be on stage for the next Democratic debate Wednesday in Nevada.
