On Thursday, Nielsen reported that the debate, which was held in Atlanta, Georgia, had more than 6.5 million viewers. That figure also included the 1.6 million in the popular 25-54 demographic.

The October 15th debate hosted by CNN received an estimated 8.5 million viewers with 2.4 million in the targeted 25-54 demographic.

CNN’s Democrat primary debates in August, which took place on two separate nights, attracted 8.7 million and 10.7 million viewers respectively.

The most-watched Democrat debate came in June, when an estimated 18 million overall viewers tuned in to see the candidates debate for the first time. Hosted by NBC, the two-day event received five million viewers in the target demographic.
