Democrats have finally decided to make judicial nominations an election issue, after essentially ceding the ground to Republicans for decades. Hillary Clinton barely mentioned Merrick Garland or the Supreme Court vacancy on the stump; this time around Democrats are going all in.

But forget the conventional play of highlighting policy areas where “Trump judges” differ from those a Democratic president would appoint: issues such as abortion, guns, affirmative action, voting rights, and campaign finance. This time, the Supreme Court itself is the target.
