Democratic presidential candidate Joe Biden is promising to expand the 2010 health insurance overhaul while blocking sweeping proposals from the left and the right.
The former vice presidentâ€™s plan allows him to go on offense against both President Donald Trump and against his more progressive rivals.
The Republican president wants to gut the Affordable Care Act. Bidenâ€™s top rivals for the 2020 Democratic nomination want to go to a single-payer system that could effectively eliminate private insurance.
Biden wants to add a public option to existing ACA insurance exchanges but not eliminate private insurance.
Biden is the only top contender who doesnâ€™t back a single-payer model, pitting him against Sens. Bernie Sanders of Vermont, Elizabeth Warren of Massachusetts and Kamala Harris of California.
