George Will Pontiac Daily Leader WASHINGTON — Looking on the bright side, which is usually irrational but occasionally justifiable, the debate about raising the federal minimum wage to $15 is mildly encouraging evidence that moderately sensible policymaking is again possible. The debate has been informed by data, not all of which has been ignored. The debate has been a reminder of federalism's importance in a continental nation. Because the debate is about money, it has revived the capacity for legislative bargaining about splittable differences. Best of all, one side in the debate has refrained from overturning legislative due process, which it could have done and the other side has hitherto done.
