With the exception of Bill Clinton's two victories in 92 and 96, Establishment, Wall Street Dems have a terrible record of winning elections over the past 24 years. The great 1994 GOP wave in Clinton's first term ended 40 straight years of Democratic control of the House, and devastated Democrats at state and local levels around the country. From 1994 to 2018, Democrats have clearly controlled the House and Senate for only 4 of the past 24 years (they did briefly control the Senate for part of the 2001-2003 term, but lost control by the end of that session). The GOP more or less set the agenda for Congress for the first six years of Dubya's Presidency. Under Obama, who upset the Establishment favorite, Hillary, but then governed mostly as a centrist, Wall Street, Establishment Democrat, the Dems suffered even greater losses in 2010 and 2014. Basically, Establishment Dems have four presidential victories (Clinton and Obama twice), and lots and lots of losses elsewhere, since 1992. I realize that progressive candidates can't win everywhere, but you can certainly argue that Establishment Democrats don't have the best track record over the last quarter-century either.
