The final debate drew a household rating of 20.4, down from 23.7 for the first debate.

Four years ago, the final debate between former Secretary of State Hillary Clinton and Trump drew 84 million viewers.

Nielsen's figures for 2020 are based on live coverage for 15 networks and includes viewers streaming on connected TVs.

Fox News Channel had the biggest audience with 14.8 million viewers. Among the other big networks, ABC had 10.8 million viewers, NBC had 10.2 million, CNN had 7.2 million, MSNBC had 6.7 million and CBS had 5.5 million.

The final 2020 Presidential debate will take place tonight (Oct. 22) as Americans get their last chance to see President Donald Trump and Democratic candidate Joe Biden meet face-to-face before Election Day.

A host of services including broadcast networks ABC, NBC, CBS, Fox, PBS, Telemundo and Univision -- along with cable networks CNN, Fox News, Fox Business, C-SPAN and MSNBC -- will air the debate live beginning at 9 pm from Nashville. NBC News’ Kristen Welker will moderate the debate. 

The debate will be the second between the two candidates. The first debate on Sept. 29 -- which was marred by numerous interruptions by the candidates -- drew more than 73.1 million viewers, according to Nielsen. For tonight’s debate, the Commission on Presidential Debates said it will mute each candidate’s microphone for two minutes as the other candidate answers moderator questions. 

The two candidates held dueling Oct. 15 Town Hall meetings after a debate scheduled for that day was cancelled by the Commission on Presidential Debates following President Trump’s COVID-19 diagnosis. 

The debate over the rules for the next presidential debate could become an academic one, or alternately move to a virtual format as have so many formerly face-to-face meetings in the age of COVID-19.

That debate is currently scheduled for Oct. 15 in Miami at the Adrienne Arsht Center for the Performing Arts, but with the President testing positive for COVID-19, he has gone into quarantine, which is usually a minimum of two weeks.

The Commission on Presidential Debates had signaled it was going to change the rules after the first debate devolved into a chaotic shouting match filled with personal attacks. The White House had suggested it didn't want the rules changed and might not participate if they were.

The President tweeted early Friday morning:

"Tonight, @FLOTUS and I tested positive for COVID-19. We will begin our quarantine and recovery process immediately. We will get through this TOGETHER!"

According to reports, Vice President Mike Pence has tested negative, so the VP debate scheduled for Oct. 7 in Salt Lake City could still go on as planned.

A debate commission spokesperson was not available for comment at press time on the status of the second debate given the President's diagnosis or whether it could switch to a virtual format.

Steve Scully, senior executive producer and political editor at C-SPAN Networks, is scheduled to moderate the second debate. 

A C-SPAN spokesperson said they had not yet gotten any official word on the status of the debate. 

While signaling Fox News' Chris Wallace had tried his best, the Commission on Presidential Debates said Wednesday it would change the format for the remaining debates--two presidential, one vice presidential.

That followed the Sept. 29 debate moderated by Wallace that devolved into a series of personal attacks and the President consistently talking over his opponent. The commission sponsors the televised debates.

"Last night’s debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the commission said. "The CPD will be carefully considering the changes that it will adopt and will announce those measures shortly."

It ended with a nod to Wallace, who was criticized for not keeping the President's outbursts better in check but also drew lots of sympathy for what most conceded would have been a herculean feat had he accomplished it: "The Commission is grateful to Chris Wallace for the professionalism and skill he brought to last night’s debate and intends to ensure that additional tools to maintain order are in place for the remaining debates."

In a joint memo to staffers, Fox News Media CEO Suzanne Scott and President Jay Wallace also had Chris Wallace's back. 

"We'd like to take a moment to thank and congratulate Chris Wallace for moderating last night's extraordinary debate," they said. "We are extremely proud of his professionalism, skill and fortitude in a unique situation while doing everything possible to hold both candidates accountable. No moderator could have managed a debate of that magnitude better than Chris."

CNN Political Analyst Bakari Sellers may have put it best when he said he felt sorry for Wallace as he attempted to "comb through the chaos" to find a debate.
