A battle is brewing in the courts over the Trump administration’s move to let states impose work requirements for recipients of Medicaid, the health insurance program for the poor. Advocacy groups are gearing up to sue the administration, arguing that it doesn’t have the power to allow work requirements and other rules for Medicaid without action from Congress.

But the administration is defending the legality of the shift. When unveiling guidance Thursday on the work requirements, top Medicaid official Seema Verma said the administration has “broad authority” under current law to allow states to make changes through waivers.

A day after the Trump administration announced that it would allow states to compel poor people on Medicaid to work or get ready for jobs, federal health officials on Friday granted Kentucky permission to impose those requirements.

Becoming the first-in-the-nation state to move forward with the profound change to the safety-net health insurance program is a victory for Kentucky’s Republican governor, Matt Bevin, who during his 2015 campaign for office vowed to reverse the strong embrace of the Affordable Care Act by his Democratic predecessor.

Mainstream Democrats are clamoring for Canadian-style single-payer health care — a demand once relegated to the far-left fringe of the party.

Sixteen Senate Democrats, including several with aspirations for the party’s presidential nomination in 2020, have signed onto Sen. Bernie Sanders’s “Medicare for All” plan. Fealty to single-payer is already proving a litmus test for Democrats running for public office in blue states like California.

The increasing idolization of our northern neighbor’s health system is ironic, as Canada’s single-payer system — which I grew up under — just experienced its worst year ever.
