I agree with folks saying that Sanders's support for the nominee in 2020 feels more full-throated, even though the Democrats' platform isn't that much more progressive than it was in 2016. It again commits to the $15 an hour minimum wage and to adding a public option to the Affordable Care Act, which isn't Sanders’s (or several other candidates’) health care position. That said, the platform does state, "We are proud our party welcomes advocates who want to build on and strengthen the Affordable Care Act and those who support a Medicare for All approach."
