Is there anyone less deserving of a “I know his heart” defense than Donald Trump? Probably not, but Mike Pence is apparently making it anyway to suggest that Trump’s “shithole” outburst wasn’t blatant racism. Friends and foes are all pretty certain at this point what’s in Trump’s heart — and Trump himself has had (and missed) countless opportunities to persuade us otherwise. But that’s not the only reason this case is laughable: From his debut as a candidate and his Mexican rapists comments, the entire Trump political brand has been built on defying “political correctness” and giving voice to the racism that’s in the hearts of too many Americans.
