CNN will have a hard time setting a ratings record for Tuesday night’s Democratic presidential debate after Republican candidates drew more than 20 million viewers in each of their first two face-offs. But the network is looking to make sure that voters have no excuse for missing the action, dedicating all of its platforms to the event it is hosting in Las Vegas.

The debate starts at 9 p.m., and Hillary Rodham Clinton will be center stage, flanked by Senator Bernie Sanders of Vermont and Martin O’Malley, the former governor of Maryland. On the ends will be Jim Webb and Lincoln Chafee, the long-shot contenders. Anderson Cooper is moderating.

The viewing options are plentiful:

The old-fashioned way – CNN’s coverage starts at around 8:30 p.m. and viewers can tune in directly to the network’s flagship channel or catch the event on CNN International or CNN en Español.

On the desktop – For those who like a bigger “second screen,” CNN.com will stream its live feed on its home page.

On mobile – Smartphone and tablet users can turn their devices into miniature televisions, streaming the program to directly to their touch-screens on CNN’s app. Cable provider logins will not be required.

On social – Facebook is teamed with CNN to sponsor the debate. To make things interactive, viewers can submit questions through Facebook or Instagram. On Twitter, the hashtag #DemDebate will provide a flood of reaction to the candidates. You can follow along with the New York Times politics team as well on Twitter @nytpolitics and on Facebook at Facebook.com/nytpolitics.

Easy listening – For debate buffs who prefer to hear the dulcet tones of Democratic candidates without all of the stagecraft, Westwood One News is airing the event live on its broadcast radio stations.
