Super Tuesday has come and gone. Supertrump continues to wreak havoc on the GOP's perception of itself, as he promises to transform the right into a mirror image of the left. The past few days confirm that each reflection of leftist values seems to increase his support among primary voters—while alienating those who have long seen themselves as the moral and intellectual leaders of the conservative movement.

On Sunday, Trump claimed—implausibly—that he lacked the information necessary to form an immediate opinion about David Duke and the Ku Klux Klan, though he did eventually disavow their support. Voters across the Super Tuesday states appeared to pay the incident little heed. Trump's best showing of the evening—by far—came in liberal Massachusetts, hardly Klan country even when the KKK was an important force in American politics.
