Our nation was founded on a bedrock principle that we are all created equal. The project of each generation is to bridge the meaning of those founding words with the realities of changing times -- a never-ending quest to ensure those words ring true for every single American. Progress on this journey often comes in small increments, sometimes two steps forward, one step back, propelled by the persistent effort of dedicated citizens. And then sometimes, there are days like this when that slow, steady effort is rewarded with justice that arrives like a thunderbolt.
