I think, from a progressive point of view, to have a Democratic Congress and a Democratic White House, and to have spent the time on Obamacare, which had real benefits, 20 million insured, but not on inequality, was a major cost to the Democratic Party, costing them their majorities, but also a bit of a cost to the country, because it didn't address the fundamental issues that led to Donald Trump and that led to a lot of unhappiness, just the continued widening inequality.

For the Democrats, they're trying to avoid having the Sanders-Clinton debate over and over again. But, to some degree, they're sentenced to that debate.
