Democratic Debate Night 2 Draws in 18.1 Million Viewers

By Sara Jerde 

The viewership numbers for Democratic primary debate night No. 2 are in, and they’re record-breaking.

Roughly 18.1 million total viewers watched last night’s debate on NBC News, MSNBC and Telemundo. Out of those 18.1 million who watched on linear TV, 10.6 million tuned into NBC, 6.7 million tuned into MSNBC, and 840,000 watched on Telemundo, according to Nielsen Fast National Data.

When it came to younger news viewers, out of the 18.1 million total, 5.3 million hailed from the Adults 25-54 demo–the demo TV news advertisers covet–and 4.4 million million were adults 18-49.


Last night’s debate featured Senator Michael Bennet (CA), former Vice President Joe Biden, Mayor Pete Buttigieg (South Bend, IN), Senator Kirsten Gillibrand (NY), Senator Kamala Harris (CA), former Colorado Governor John Hickenlooper, Senator Bernie Sanders (VT), Representative Eric Swalwell (CA), author Marianne Williamson and entrepreneur Andrew Yang.

On the digital front, last night’s debate attracted 9 million live stream viewers, and 14 million video views across all platforms, including,,, NBC News NOW on OTT devices, Facebook, Twitter and YouTube.

When it came to 2016 election cycle, the first Republican primary debate aired on Fox News Aug. 6, 2015, and delivered a whopping 24 million total viewers, making it the most-watched non-sports basic cable telecast since Nielsen started measuring audiences in the mid-1980s. The inclusion of then-celebrity businessman Donald Trump and the fact the debate only featured the top 10 candidates surely played a role in these huge numbers.

The 2016 campaign was most certainly an outlier relative to past cycles.

The 2012 debates featured only Republicans, as then-President Barack Obama was still in office and not being primaried by his fellow Democrats. The first Republican primary debate took place on May 5, 2011 and aired on Fox News. It delivered 3,528,000 viewers.

The most-watched primary debate of the 2012 season aired on ABC in December of 2011. That one delivered 7.6 million total viewers.

With George W. Bush leaving office, the 2008 cycle featured both Democratic and Republican primary debates.

The first primary debate of the ’08 cycle was a Democratic primary debate which took place on on April 26, 2007 and aired on MSNBC. It hauled in 2,261,000 viewers. The first 2008 Republican primary debate which took place on August 5, 2007, and hauled in roughly 2.2 million total viewers.

The most-watched primary debate in the 2008 cycle aired on ABC and attracted 10.7 million viewers. It also took place in April of the actual election year, when interest is traditionally higher, particularly among casual news consumers.
