Trends are determined by an algorithm and, by default, are tailored for you based on who you follow, your interests, and your location. This algorithm identifies topics that are popular now, rather than topics that have been popular for a while or on a daily basis, to help you discover the hottest emerging topics of discussion on Twitter.-Twitter FAQ
Over the course of the Democratic Debate, the candidate that people left with the most interest in was Rep. Tulsi Gabbard. Just look at these maps posted by Google Trends before and after the debate.
Many Americans also were confused when they saw, despite this, that every candidate was trending on Twitter except Tulsi Gabbard.

I would like to note that Assad was more than likely trending because people were talking about Tulsi meeting with him. However, why wouldn’t Tulsi be trending higher as a result? Did people just Tweet the word “Assad” and call Tulsi “She who shall not be named”?
It took until forty minutes after the debate for Tulsi to start trending, where she was all of a sudden #2.
And that was only after many Twitter users called out this clear act of election meddling.
Here’s hoping this ends up like when Twitter tried deleting Trump’s account.
