President Obama offered his prescription Thursday for how to fix Obamacare: Expand it.

In a major speech defending his Affordable Care Act just days before the law’s fourth enrollment season starts, Obama laid out a list of measures he said would help expand coverage to the remaining 10 percent of people who still lack insurance. Most of them involve expanding parts of the law, such as convincing holdout states to accept its Medicaid expansion and increasing the subsidies for buying coverage.
