I think the classic example of this is when he got to the point of saying Obama founded ISIS, if you watch that clip you can see that all he does is react to the crowd.
The thing is he has even told the crowd that's exactly what he's doing. At one rally he remarks on the lock her up chant for Hillary. Saying he just tried it, didn't actually believe it, it went over big so he just kept going with it. He tells them that he's just telling them what they want to hear and apparently that is what they want to hear.
