Maybe I'm just too young to remember, but I've always been baffled by how the Clintons cause conservatives to literally start frothing at the mouth, even more so than Obama. The chud hate for Obama is understandable because he masqueraded as a progressive reformist. But, its more confusing with the Clintons because they are both right wingers.
Bill Clinton destroyed the last vestiges of the New Deal movement within the Democratic party and made it a fully neoliberal party, slashed welfare spending with Republican support, deregulated banks, and signed the crime bill which led to the mass incarceration of black people.
Hilary Clinton is a right wing warmongerer who made racist dog whistles during the 2008 campaign. Hell, she didn't even come out in favor of same sex marriage until like 2013.
Given that conservatives have run America's foreign policy since FDR died, that does kind of makes sense.
