> locked up hundreds of thousands of poor black people to court skittish suburbanites
That's an utterly meaningless comparison. Bill Clinton was a governor with terrible policies concerning minorities [1], while Donald Trump was a real estate mogul with terrible policies concerning minorities. The fact that their different leadership positions meant that Trump could harm a statistically fewer number of people means exactly nothing.
"Didn't lock up any black people" isn't exactly an achievement for someone who hasn't served in government.
[1]: I agree with you that Bill Clinton deserves to be held completely accountable for his actions as Arkansas governor.
