Scores of Americans are losing their health insurance along with their jobs. Here's what the 2020 presidential candidates would do for them.

The biggest difference between Biden and Sanders is their view on the employer-based system of health coverage currently in place. Biden wants to keep it, while the Vermont senator wants to toss it out and replace it with Medicare for All.

Much of the Biden plan is anchored on improving Obamacare. It would ramp up federal subsidies to make insurance plans cheaper for people to buy on the state exchanges, while also lifting the income threshold, allowing more to qualify for them.

It would also create an optional government health plan to compete with private insurers.

Those living in states that chose not to expand Medicaid would automatically be enrolled into the "public option."

Trump hasn't released a healthcare plan since he tried to repeal the Affordable Care Act in 2017.

But his administration staunchly supports efforts to weaken the law, such as by introducing short-term insurance plans that don't cover people with pre-existing conditions or many types of pricey hospital care.

He also backs a lawsuit that would completely eliminate it.

Over 20 million people could lose their coverage as a result — and insurers would be able to deny medical coverage for pre-existing conditions and jack up prices for sick people.

However, Trump has been adamant he would protect pre-existing conditions, though it's not immediately clear how.
