As a Democrat since Adlai Stevenson ran for president, I am proud that Sanders — a “democratic socialist who has never identified as a registered Democrat’’ (“Endorse, Warren, Endorse,’’ Opinion, May 5) — refused to accept the party’s label. For the past 30 years, the Democratic Party has let the poor and working class slip into poverty while doing nothing to prevent the appalling income inequality that exists in our country, the lack of universal health care, failing infrastructure, etc. He had good reason not to back the party that supported Wall Street and millionaires. Meanwhile, Sanders has caucused with the Democrats consistently and tried to amend many bills so that the poor, the working class, and veterans would be treated more fairly. He has been more of a Democrat, standing up for the principles that used to characterize the party, than the regulars. We need both Sanders and Warren to create the nonviolent revolution that is long overdue.
