I have yet to hear a strong case for the evil of Hillary. Most of the stuff that people claim has been debunked...sometimes by republicans (see Benghazi). She's a political pragmatist who tries to triangulate positions like Bill did. That can certainly be seen as slimy, but it's no different from what everyone does.

I would argue that the Clintons have done more damage to the liberal/progressive movement in the US than any family in history. In the 1970s even the Republicans made progress under guys like Nixon with the EPA, Clean Air and Water Acts, OSHA, Endangered Species Act, they even tried to get a Guaranteed Minimum Income to replace Welfare. Then the 1980s happened, well, Reagan. But it is without question the Clintons who commandeered the supposedly liberal party and moved it to the right to the same corporatist positions that plague the GOP. Who passed NAFTA? Who gutted welfare? Who passed DOMA? Who passed Don't Ask Don't Tell?
Hillary Clinton is arguably worse because unlike Bill Clinton she hoped on board with what the neoconservatives were selling in the foreign policy aisle and wasn't just a vote but one of the leading voices in the Democratic Party in 2002/2003 during the build up for war. She helped get the Democrats on board with Bush's team while they tossed aside two centuries of American foreign policy of not invading countries unilaterally. Then in 2011 she helped drag the Obama administration into getting involved in Libya. She is a neoconservative.
Hell she helped campaign for Barry freaking Goldwater. She is not a liberal. She is not a progressive. She is a power-hungry corporatist. It's bad enough that Congress is completely owned by their donor daddies, but the Clintons put everyone to shame with how in bed (literally, with Bill) they are with the special interests.
