With Republicans controlling both ends of Pennsylvania Avenue next year, they have a great, and rare, opportunity for reform. The question now is whether Donald Trump and a new congressional generation can enact center-right reform solutions, and the first proving ground will be ObamaCare. If Republicans don’t repeal the law immediately, the danger is that the natural inertia of Congress takes over and nothing changes. But the more time they put between repeal and replace, the more the danger will grow. Now’s the chance to show they can reform the entitlement state with solutions that improve the daily lives of Americans.
