Now let's go back to the big debate emerging over the health care law, and explore some of the key ideas behind the Republicans' plans.

The House bill does keep some of the most popular provisions of the law, like preventing insurers from denying coverage for preexisting conditions. It still has penalties for a lapse in coverage, but it doesn't mandate coverage in the same way. It also shifts how the government would provide financial help, while eventually reducing the number of people on Medicaid.

John Yang picks it up from there.
