I also thought he was acting as a Troll to wipe out Hillary's competition. As Trump was friendly with the Clintons. However, I guess he was only friendly as it served him to be friendly. It was interesting to see how at first the media loved him both for the ratings and also for how he was clearing a path for Hillary, or so they thought.

Trump just hit it at the right time and he tapped onto a lot of anger many Americans were feeling. He was even surprised himself and then just went with it. At least that's what I thought.
