Critical Race Theory is not exactly what I'd call radical, considering it's what's underpinned the modern argument for affirmative action.
I believe affirmative action proponents generally argue that it's supposed to be only a tie-breaking measure used in the case of two equally-qualified applicants, whereas this man was actually arguing for outright quota systems and hiring/admittance of less-qualified applicants.
That may be the guy's political position, but the idea of Critical Race Theory (power dynamics, institutionalism and race and stuff) is still the main justification for affirmative action these days. Basically, he's radical doctrine leads to moderately left-of-center to leftist-but-non-revolutionary political positions. Damning?
When you consider Critical Theory is explicitly Marxist, it's not out of the mainstream in the academic world, but it's not a great thing for a national politician to be associated with.
