Families USA says Trump's election means it is on a "Total War Footing" in a fight to save the Affordable Care Act.

Twenty million Americans who didn't have it before got healthcare insurance under the ACA.

Families USA says pealing this law will have tragic consequences for tens of millions of people. The group says it will fight hard to try to stop the repeal.

Limits on insurance company behaviors like denying coverage or hiking rates for previously existing conditions or removing lifetime limits on coverage would be wiped out if the ACA is repealed.
