There’s been precedent with nearly every president since Nixon. I’d maybe leave out Jimmy Carter, but even has skeletons in his closet. Reagan, Bush, Bush II, and Obama all had scandals and criminality that were minimized. I find it odd that people don’t realize that Obama continued some of the worst aspects of the Bush administration. It’s why I pegged it at sixty years. There was absolutely corruption before Nixon, too, but it became more egregious after him.
EDIT: Getting downvotes because I guess people have rosy memories of Obama? Obama told me whose team he was on the second he said “We need to look forward, not backward” at not prosecuting anyone in the Bush admin for lying to the world about WMD’s and leading us into an illegal and wasteful war in the middle east, a war that Obama ramped up drone warfare in. As if that wasn’t a precedent of ignoring Republican crimes that lead us to exactly where we are fucking now with everyone treating Trump with kid gloves. Bush and Cheney are literal fucking war criminals, and people cooed over how cute it was that Bush shared candy with Michelle Obama. Give me a break. That shit is precisely what lead us here, treating war criminals with kid gloves.
