2016 Democratic Party Platform, healthcare:

2016 Democratic Party Platform (DRAFT)

Universal Health Care

We believe as Democrats that health care is a right, not a privilege, and our health care system should put people before profits. Thanks to the hard work of President Obama and Democrats in Congress we took a critically important step towards the goal of universal health care by passing the Affordable Care Act (ACA), which has offered coverage to 20 million more Americans and ensured millions more will never be denied coverage on account of a pre-existing condition.

We will keep costs down by making premiums more affordable, reducing out-of-pocket expenses, and capping prescription drug costs. Democrats will also work to end surprise billing and other practices associated with out-of-control medical debt that lead to unconscionable economic strain on American households. We will offer relief so Americans do not face high costs, and we will fight back against insurers trying to impose excessive premium increases.

No mention of medicare for all, single payer, just support for the ACA.

2017: Nancy Pelosi, House Minority Leader on medicare for all:
“No, I don’t,” Rep. Nancy Pelosi (D-Calif.) promptly said, when asked by a reporter if she thinks single payer should be in Democrats’ 2018 party platform.
