Bernie Sanders is unquestionably in the top tier of candidates for the Democratic nomination, and it would be an epic act of self-destruction for Democrats to plunge into an internecine conflict over his candidacy at a time when they need to marshal every asset to defeat Trump and his GOP cronies. I am calling on Democrats, progressives, and leftists to hit the pause button, to table our disagreements, no matter how intense, as we fight to preserve the rule of law and the last semblance of our democracy. We owe it to ourselves and our country.
