Democratic presidential candidates Vermont Senator Bernie Sanders and former Secretary of State Hillary Clinton faced off Thursday night in the first Democratic debate since Sanders’ decisive victory over Clinton in Tuesday’s New Hampshire primary and drew sharp distinctions between each other on everything from foreign policy to how they plan to pay for the programs they’ve proposed, to campaign finance reform. Our two guests respond. Reacting to Clinton’s claim she helped negotiate a ceasefire in Syria, Jeffrey Sachs argues, "She has backed a CIA-led attempt at regime change that has led to a bloodbath there." Sachs is a leading economist and the director of The Earth Institute at Columbia University, whose recent article for The Huffington Post is headlined "Hillary is the Candidate of the War Machine." He adds that, domestically, Clinton "is basically saying the status quo is just fine." But New York Congressmember Gregory Meeks, chair of the Congressional Black Caucus political action committee, which has just endorsed Hillary Clinton, says Sanders has promised change that he will be unable to deliver. "If you’re running on just a dream, and not how you can do something in reality, then I think that is misleading the American people," Meeks says.
