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.
mostly it's culture war bullshit and narcissism of small differences, but also bill clinton was incredibly popular during his presidency. he was obama before obama. clinton and the democratic third-way strategy successfully ate the right's lunch. with the end of the cold war and the dawn of the end of history, the GOP found itself in an identity crisis. the cosmic ideological struggle against the forces of evil had been won, so a new enemy needed to be relocated within. the actual nefarious details of the clinton's lives happened to align with the undercurrent of evangelical conspiracy-theorism that the previous era's bircherites evolved into. also a lot of the hate towards hillary was catalyzed by misogyny over a professional woman in a position of power. that was a thing people used to get real mad about, moreso than today. it's just a coincidence that she genuinely is a baby eating satan worshiper.
