WASHINGTON — Sen. Bernie Sanders, I-Vermont, will run for president proposing to enact a “Medicare for All” health care system, stave off catastrophic climate change through a “Green New Deal” and other climate measures, and implement a $15 an hour minimum wage for all American workers, according to aides to the senator. Sanders will also tout proposals to mandate breaking up the biggest Wall Street banks; free tuition at public colleges; lower drug prices with aggressive government intervention; new labor law to encourage union formation; curbed corporate spending on elections; paid family and medical leave; gender pay equity; and expanded Social Security benefits for the elderly and disabled, aides said. Sanders’ criminal justice platform will include legalizing marijuana, ending cash bail throughout the U.S., and abolishing private prisons, while he will also run on the standard Democratic policy goals of protecting young immigrants brought to the U.S.
