Donald Trump’s tone may be unprecedented in American politics, but his policies aren’t. Barack Obama restricted the movement of citizens from the seven Muslim countries that ended up on Trump’s travel ban list. The wall that Trump wants to build along the Mexican border is an extension of Bill Clinton’s Operation Gatekeeper. Trump’s rampaging deportation machine was bequeathed to him by previous administrations, including Obama’s. And Trump is hardly America’s first racist president. Even his ‘shithole countries’ comment is not new.
