In these last eight years, 14 Republican debates have been held. The most watched was on Aug. 6, 2015, which obtained around 24 million viewers. It was the first in which Trump participated before going on to win the presidential election that took him to the White House. The debate from Sept. 16, 2015 (23 million) and Dec. 15, 2015, (18 million) were the next most watched.
