Ten of those candidates debated last night in Detroit. Tonight, 10 more candidates will be onstage, including at least four contenders with direct connections to the New York area: Mayor de Blasio , Senator Kirsten Gillibrand, Senator Cory Booker and the entrepreneur Andrew Yang .

(Night 2 will also include former Vice President Joe Biden; Senator Kamala Harris of California; Senator Michael Bennet of Colorado; Julián Castro, the former housing secretary and former mayor of San Antonio; Gov. Jay Inslee of Washington; and Representative Tulsi Gabbard of Hawaii.)

There are many ways to watch tonight’s debate, which will air on CNN, CNN en Español, CNN International and streaming services at 8 p.m. Eastern Time: on closed caption, with a bottle of good rosé; with the volume turned up to 11 while tweeting in all caps; or under a ceiling fan with background music.

(I recommend the instrumental version of “The Message” by Nas, which samples Sting’s “Shape of My Heart.”)

Here are some other options:

Some candidates had events listed on their websites; these events may be independently organized.

Mr. Biden’s site: Shades of Green Pub (125 East 15th Street , Manhattan) with the Samuel J. Tilden Democratic Club.
