The biggest boost proponents of Medicare for All—basically every Democrat who matters these days—could ask for is a Trump administration intent on shrinking the government's role in health care. At the same meeting in which Trump's Health and Human Service Secretary vowed unending war on Medicaid, he also said that the administration's goal for "reforming the American health care system" was to get government out of it.
Which bodes poorly for Medicare as well as Medicaid. "Medicare is running out of other people's money," he told the crowd, "and those other people happen to be our children." Which is an out-and-out lie—there's not "other people's money" when it comes to either Medicare or Social Security. It's all of our money, paid in for a secure future. Azar wasn't directly signaling the administration's plans for Medicare there—he didn't have to. It's understood in the Republican universe that destroying Medicare as we know it is the mission.
Seema Verma, the administrator of the Centers for Medicare and Medicaid Services, continued with a variation on that theme to pretend like they're doing all this just to protect seniors. Medicare, she told the Commonwealth Club in San Francisco, is for "a very specific population" of seniors and people with disabilities. Expanding it with Medicare for All would "run the risk of depriving seniors of the coverage" and "would only serve to hurt and divert focus from seniors. … In essence, Medicare for all would become Medicare for none." Which, to be honest, would be just fine with the Trump team. That or "Medicare for people who can buy it on their own."
Meanwhile, they are gleefully taking their wrecking ball to the Affordable Care Act, to Medicaid, to Medicare and freaking the American electorate the hell out over it. Voters are well aware that Trump is actively engaged in sabotaging the ACA and that means the protections they've come to rely on are in jeopardy.
An electorate who is worried about the loss of their health care is also thinking about health care, and the trend since Trump took office, according to Civiqs data is toward expanding the law and the government's involvement, not ending it.
We've reached an inflection point where expanded Medicare isn't a radical proposal. Trump's sabotage is at least in part to thank for that.
