ObamaCare is performing worse than expected when it became law: plans are less attractive, enrollment is lower, premium increases are higher, and risk pools are sicker. Medicaid expansion is a key problem with the law. The main problem with Medicaid, which existed before the ACA took effect, is that enrollees receive little value from the program. The joint federal-state health care program needs large scale reform so that it provides better value for both enrollees and taxpayers.
