If you are in the search for silver linings, one benefit of Sen. Bernie Sanders (I-Vt.) pointlessly continuing his losing campaign is the freedom for Democrats to denounce him and his anti-party escapades. After years of humoring him, the vast majority of Democrats, from super-progressives to moderates, can now say out loud what they’ve said quietly: It has always been about Bernie. It’s not a movement, but rather a vanity project. ....

The problem, according to many Democrats, remains that 15 percent of Sanders supporters say in polling that they would vote for President Trump over Biden. This nugget actually makes the opposite argument: There is nothing that would satisfy some faction of the Sanders coalition that would rather blow up our democracy and reelect Trump. With people so irrational, the best response is to ignore them. They, like the MAGA-hat crowd, are unreachable and cannot be bargained with (e.g., more New Green Deal talk!). So do not try. No more outreach to Sanders, no more promised policy modifications, no more speaking slot at the convention. Enough

This would have some salutary effects.

First, it would make perfectly clear that Biden is not Sanders and not a crazy left-winger, as Trump would like to paint him in the campaign. Biden makes a sharp distinction between the “democratic socialist” crowd and his own brand of center-left politics. Since he cannot get the 15 percent of “Bernie or Bust” Democrats (or independents), he might as well make a strong play for moderate independents and disaffected Republicans. Cutting Sanders off effectively allows Biden to pitch to gettable swing voters, not waste time on unattainable Bernie Bros.

Second, freezing out Sanders will make governance in a Biden administration much easier and more cohesive. There will be no debt to be paid to Sanders, no advisers taken on to satisfy Sanders, and no weird and distracting policy initiatives to lead the new administration astray. This would be a center-left administration confident of its own governing agenda — and personally cohesive.

Third, it would free up constructive, smart progressive leaders such as Sen. Elizabeth Warren (D-Mass.) to lead that wing of the party. She has already begun that process, contributing bankruptcy and student loan forgiveness plans to the Biden campaign. With a practical, crafty progressive in the Senate (hopefully in the majority and able to lead on legislation), Biden would be able to broaden his appeal and cultivate allies in the Warren wing of the party.

In other words, shoving Sanders offstage opens up room for party builders and party reformers, putting aside unattainable proposals (e.g., Medicare-for-all) in favor of a smarter, more broadly acceptable agenda. (Biden would not need to fend off a Warren primary challenge, as Barack Obama did with Sanders in 2012.)
