Re “Odds Longer, Sanders Pushes On From the Left” (front page, March 12):

As a member of the Sanders-Warren wing of the Democratic Party, I’m not excited about Bernie Sanders staying in the race and getting walloped in Florida. He could do something really dramatic at Sunday’s debate: Endorse Joe Biden, but say progressives are going to hold him to the progressive positions he has taken in the campaign on major issues like labor law reform, taxes and climate change.

I think in his heart he believes in those positions, but if he’s really thinking about making Jamie Dimon the Treasury secretary (for example), there’s reason to worry about whether he’ll stick to them.

Progressives need to make it clear that we’ll work like dogs to help Mr. Biden beat President Trump, but we expect him to honor his commitments. Mr. Sanders has the megaphone to deliver that message loudly.

I firmly support Bernie Sanders’s desire to stay in the race. Not until we see the two front-runners stand toe to toe in the debate on Sunday will we be able to judge who best can lead our country and who can take down Donald Trump. The media tells us one man’s nomination is inevitable. Isn’t that up to the voters in the primaries yet to come?
