The third GOP debate had 14 million viewers, which is ten million less than the first two debates. Two factors: the World Series was playing at the same time, and it wasn’t available for online streaming.
It also didn’t do as well on social media, with only 1.8 million tweets compared with the 3.9 million during the second debate.
Here are the twitter rankings:

  1. Donald Trump 201,978
  2. Ted Cruz 200,151
  3. Ben Carson 148,131
  4. Jeb Bush 85,203
  5. John Kasich 66,213
