Some Senate Republicans want to get rid of the Affordable Care Act entirely. Others don't want to cause 22 million Americans to lose their coverage, as the Congressional Budget Office predicts will happen if the Senate version goes into effect.
What should be the Democrats' response? Over the coming weeks or months, Democrats must continue to defend the Affordable Care Act. It's not perfect, but it's a major step in the right direction. More than 20 million Americans have gained coverage because of it.
But Democrats also need to go further and offer Americans a positive vision of where the nation should be headed over the long term. That's toward Medicare for all.
Some background: American spending on health care per person is more than twice the average in the world's 35 advanced economies. Yet Americans are sicker, our lives are shorter, and we have more chronic illnesses than in any other advanced nation.
That's because medical care is so expensive for the typical American that many put off seeing a doctor until their health has seriously deteriorated.
Why is health care so much cheaper in other nations? Partly because their governments negotiate lower rates with health-care providers. In France, the average cost of a magnetic resonance imaging exam is $363. In the United States, it's $1,121. There, an appendectomy costs $4,463. Here, $13,851.
The French can get lower rates because they cover everyone — which gives them lots of bargaining power.
Other nations also don't have to pay the costs of private insurers shelling out billions of dollars a year for advertising and marketing — much of it intended to attract healthier and younger people and avoid the sicker and older.
Nor do other nations have to pay boatloads of money to the shareholders and executives of big for-profit insurance companies.
Finally, they don't have to bear the high administrative costs of private insurers — requiring endless paperwork to keep track of every procedure by every provider.
According to the Kaiser Family Foundation, Medicare's administrative costs are only about 2 percent of its operating expenses. That's less than one-sixth the administrative costs of America's private insurers.
To make matters even worse for Americans, the nation's private health insurers are merging like mad in order to suck in even more money from consumers and taxpayers by reducing competition.
At the same time, their focus on attracting healthy people and avoiding sick people is creating a vicious circle. Insurers that take in sicker and costlier patients lose money, which forces them to raise premiums, co-payments and deductibles. This, in turn, makes it harder for people most in need of health insurance to afford it.
This phenomenon has even plagued health exchanges under the Affordable Care Act.
Medicare for all would avoid all these problems, and get lower prices and better care.
It would be financed the same way Medicare and Social Security are financed, through the payroll tax. Wealthy Americans should pay a higher payroll tax rate and contribute more than lower-income people. But everyone would win because total health care costs would be far lower, and outcomes far better.
If Republicans succeed in either gutting or subverting the Affordable Care Act, the American public will be presented with a particularly stark choice: expensive health care for the few, or affordable health care for the many.
This political reality is already playing out in Congress, as many Democrats move toward Medicare for all. Most House Democrats are co-sponsoring a Medicare-for-all bill there.
A Gallup poll conducted in May found that a majority of Americans would support such a system. A poll by the Pew Research Center shows that such support is growing, with 60 percent of Americans now saying government should be responsible for ensuring health care coverage for all Americans — up from 51 percent last year.
Democrats would be wise to seize the moment. They shouldn't merely defend the Affordable Care Act. They should also go on the offensive — with Medicare for all.
