Even in this early stage of the 2020 race, nearly all of President Donald Trump's would-be opponents have staked out their support for expanding health-care coverage.
But not all of their proposals are alike. And while many of the 2020 challengers say they want to implement some form of "Medicare for All" or "universal health care," worlds of difference emerge in the details of what exactly those phrases mean in practice.
Public support is just as variable, depending on how the policy is presented — and to whom.
A Kaiser Family Foundation poll from January, for instance, found broad support for expanding the government health insurance program Medicare to include a buy-in option for ages 50 to 64. And an "optional" Medicare for All plan received nearly identical support. But Medicare for All by itself received a much slimmer 56 percent majority, and support sank when respondents were asked if they would oppose that plan even if it required most Americans to pay more in taxes.
