The signs are everywhere this morning: The Clinton and Sanders camps are now signaling how the Democratic primaries might wind down without too much noise, contentiousness, disruption, and anger.

Rep. Keith Ellison, a top supporter of Bernie Sanders who is also the co-chair of the Congressional Progressive Caucus, suggested the Clinton camp had some work to do in order to appeal to Sanders’s supporters. But he also carefully noted that Sanders would not do anything to imperil the party unity that will be required to defeat Donald Trump. “Every Bernie supporter knows that this Supreme Court issue is looming. We’ll have party unity….everybody has a responsibility to make sure there will never be a President Trump. Bernie has been around a long time….he’s not going to hand this country over to Donald Trump.”

On the Clinton side, the Post reports that a top Clinton backer, Senator Dianne Feinstein, is now calling for both camps to “work together, across our party, to have a platform that represents the views of Democrats.”

In 2008, after the divisive primary season concluded, Feinstein opened her Washington manse to host a secret unity meeting between Obama and Clinton. She said she would reprise that role for Clinton and Sanders. “I’d be very happy to offer that,” Feinstein said.

The other day, another top Clinton backer, Senator Sherrod Brown — who has great credibility among economic progressives — also offered in an interview with me to take part in any negotiating efforts to unite the camps. He even suggested that Clinton “should work with him on the platform,” and offered some areas of common ground they could reach on financial reform (an area of real disagreement), such as how to toughen up Dodd-Frank’s requirements for big banks’ plans to wind down in a crisis.
