Will Sanders’s fights continue to be Clinton’s fights? Certainly, Sanders has steadily pushed Clinton to the left. She will probably keep pressing issues like trade and the minimum wage during the rest of the campaign, and she promised on Tuesday to pursue them as president. But we all know what happens to campaign promises.

The Clinton campaign gave in to Sanders on some of these issues in the drafting of the Democratic Party platform over the weekend, and her concessions will keep the peace at the Democratic National Convention in Philadelphia at the end of this month.

There will be the ritual first-round votes in which the Great State of Whatever proudly casts its votes for Sanders. But in the end, the platform will be adopted, Sanders will get his prime-time speaking slot, Clinton will be nominated and that will be that.

The question for Clinton is how many of the 13 million people who voted for Sanders will vote for her — indeed how many of them will vote at all. Motivating that crowd is going to be the big challenge for Sanders if he was sincere on Tuesday when he promised to help Clinton get elected.

He may need a different formula from the one he used on Tuesday — talking about the things on which he and Clinton now agree, and ignoring the ones on which they disagree.

“I have known Hillary Clinton for 25 years,” he said. “I remember her as a great first lady who broke precedent in terms of the role that a first lady was supposed to play as she helped lead the fight for universal health care. I served with her in the United States Senate and know her as a fierce advocate for the rights of children.”

What about her time as secretary of state? Sanders called his former opponent “Secretary Clinton” a couple of times, but never mentioned the State Department, probably because he has relentlessly attacked her over her record in that job.

If his primary aim is to keep alive his cult of personality, perhaps all Sanders can do is accentuate the positive and eliminate the negative. I’m not sure that will get his supporters to vote in November.
