This will make it possible for the Republicans to do away with the Affordable Care Act. With that, insurance companies will be able to deny coverage because of a pre-existing condition like diabetes, covid-19 etc. You will also lose coverage for your adult children.
Please know also that the Republicans have no plan. Get that? After 10 years they still have no plan for a replacement for the Affordable Care Act.
Remember also that a Republican promise is worth nothing as evidenced by the nomination of a Supreme Court replcement for Ruth Bader Ginnsburg with a presidential election 40 days away. They denied Obama a Supreme Court nominee because it would be within the same year as an election.
