Are you sure it's not the systemic political corruption plaguing both sides? The preponderance of money in politics? The fact that the common person feels ill-serviced by both parties? What else would explain why progressive policies and Bernie, including their respective stances on campaign finance, are so popular as both parties languish and heatedly compete for being least popular?
Free trade, deregulation of labour and industry sectors, crime enforcement/corrections privatization, welfare/reform, transition of welfare to workfare to name a couple; some concrete examples from the New Dem wiki article exploring key aspects of Bill Clinton's legislation:
The multi-lateral free trade deal NAFTA
The federal “Defense of Marriage Act” that prohibited the federal government from recognizing same-sex marriages (ruled unconstitutional by the U.S. Supreme Court in 2013)
Major reforms to the American welfare system (still in effect)
The Violent Crime Control and Law Enforcement Act, sometimes referred to as the 1994 Omnibus Crime Bill[19] (many provisions are still in effect)
New Democrats were also more open to deregulation than the previous Democratic leadership had been. This was especially evident in the large scale deregulation of agriculture and the telecommunications industries. The New Democrats and allies on the DLC were responsible for the ratification of the North American Free Trade Agreement (NAFTA).
Moreover, Clinton was responsible for the partial repeal of Glass Steagall, and strangled derivatives regulation in its cradle (which as it turns out, was a patently bad idea come 2007-8).
