Sol: I know you're a Hillary supporter, and you've asked before what people have against her, so while I can't answer your above question (I agree that the "run America into the ground" is hyperbole), I can tell you some of the things that bother me about her:
I think Hillary will continue the terrible civil rights violations started by GW and continued and extended by Obama, specifically re: The Patriot Act, the NSA, TSA, Department of Homeland Security.
I think Hillary is owned by Wall Street, and will continue moving America towards an oligarchy controlled by a few elite corporations and their lobbyists.
However, I just fear she is more of the same, as bad or worse as the last two, and marching us down a path of 1984-esque dystopian ideals.
I think nearly any candidate from either major party would do the same, though she will be even more blatant about it, because she's known to be that way, and will still have been elected (if she is), so she'll take that as tacit approval. I think the two parties are very similar when it comes to many major issues (campaign finance, big government being a few), and they play up the more minor ones to divide voters.
