Approximately 9.3 million people tuned in to watch the debate on Fox, Fox Business and Univision. That’s a drop of 27% from the first debate which had 12.8 million viewers.

[…] Even though it was broadcast on Fox Business Network, Fox News Channel and Univision, it still attracted roughly 3.4 million fewer viewers than the first GOP debate just one month ago, which was hosted by the Fox News Channel. That’s a decline of 27%. By contrast, the decline between the first and second debates of the 2016 cycle — both of which featured Trump — was just 4%. (link)
