Trump or Hillary as President, who else is petrified?

[Genersis]

To me it seems there are four groups of people that Trump is notably popular with:

1) People who see him as a character, a funny guy; I mean so he likes to exaggerate? He seems cool, speaks his mind and was on The Apprentice, so...

2) Other people who genuinely agree with him. Far right folk. fascists and authoritarian types.

3) Some moderates who have taking a liking to him just because a few positions he holds are to the left of most Republicans.(especially on healthcare, if I remember correctly?)

4) And lastly a group of people who like him because he's a political outsider. Anti-establishment.
The Libertarian/Ayn-Randian types(that he's stinking rich, a "self-made man", also attracts such folk)

I could be completely wrong, but that's the jist I get.

I currently think he would lose to Clinton by a comfortable margin.
As for Sanders...I couldn't say.
That Socialist Shtick didn't seem to hurt Obama much, but then it wasn't as true for Obama...
