What will happen to the world when Trump takes over from Obama?

I also don't know. Maybe he's being infamous created an impact to some people. Maybe some also decided to change their preference or maybe they felt like there's something that Trump can offer. We'll never know.

I think the answer why people are crediting him with their support is showmanship. People like the image of someone who keeps doing all sorts of publicity stunts, showing off in front of the cameras. And here, someone who's been on TV for ages can achieve a pretty good rating... Little they care about anything else...
