President Donald Trump said months ago he’d release a shortlist of Supreme Court prospects by Sept. 1. That deadline came and went this week with no list.

It’s not the first time the president has committed to and then blown through a self-imposed deadline. Whether it’s a health care plan, tax legislation or an infrastructure bill, Trump has a tendency to issue a timeline — often “two weeks” — that doesn’t materialize.

But the Supreme Court promise comes on a central issue for the president, one that helped him win the White House after he released a shortlist of prospects in May 2016 that rallied conservative and evangelical voters — a coalition he’ll need to re-assemble to stay in the White House.
