Tonight, 7 Democratic candidates for the White House meet at the last debate of the year, hosted by POLITICO and PBS Newshour. In the last part of our series, we discuss their climate proposals, and how the Democratic field differs from the current administration’s agenda. Plus, FERC will vote on whether or not to impose a price floor on PJM interconnection's capacity market, a decision that could redefine the regional transmission organization.
