Make no mistake. Senator Elizabeth Warren wants the nation to have a single-payer government-run health insurance plan (commonly called Medicare-For-All). She truly believes that kind of plan will be the best for all Americans -- covering all citizens with decent insurance and lowering the cost of drugs and medical care.
But Warren is also a realist. She understands that a Medicare-For-All plan could not pass Congress right away if she's elected -- even with Democrats in control of both branches of Congress. Too many Americans get their private insurance through their employer, and they like the plan they have. A true Medicare-For-All plan could not be initiated until these people are convinced it would be better for them.
That does not mean that Obamacare could not be improved to cover all Americans and start to lower costs. In fact, most Americans would support a government public option for health insurance -- one that would cover anyone who can't afford private insurance and would allow any person to buy into the plan. And such a plan could be easily passed with a Democratic president and a Democratic-controlled Congress.
So Warren has made it clearer what she supports, and what she would try to achieve if she became president. She says she would first get a transition plan passed -- a public option that would cover those without insurance and that any American could buy into. She believes this step would convince most Americans that Medicare-For-All could work, and then it could be passed.
Here, from her website, is how she describes what she would do for health insurance if elected president:
