Single-payer health care is a dividing line in the race, separating Democrats who want to replace the private insurance system from those who favor improving it. Some candidates — like Bernie Sanders and Michael Bennet — picked a clear side. Others, like Elizabeth Warren and Kamala Harris, took a middle path.

Despite all the hoopla about Obamacare and its individual plans, most working-age Americans still get their health insurance through their employers. And as countless health wonks have noted, there are lots of problems with that. Employer offerings are limited and are not portable when people switch jobs. And the tax advantages that perpetuate this situation distort the economy: They encourage companies to offer more and more compensation in the form of health benefits, and they are unfair to workers without access to employer plans.

Rising support for socialism in the United States comes at a time when politicians like Sen. Bernie Sanders, I-Vt., promise a great many “free” services, to be provided or guaranteed by the government.

Supporters often point to nations with large social programs, such as Canada, the United Kingdom, and the Scandinavian states, particularly when it comes to health care.

Never mind that these are not true socialist countries, but highly taxed market economies with large welfare states. That aside, they do offer a government-guaranteed health service that many in America wish to emulate.
