httpv://www.youtube.com/watch?v=eb-EMFb0UKM  Today is the day we celebrate the birth of Dr. Martin Luther King, Jr. I was able to observe what would have been his 83rd birthday in two ways that helped me feel connected to his spirit (and to the spirit of the two people who taught me most about what he stood for, my mother and father). First, I wrote a piece at the Voice about how I think MLK would have stood with many of the people we profiled in the list of the “100 Most Powerless New Yorkers.” Later this morning, I had the honor of appearing on the Brian Lehrer Show’s MLK day broadcast on WNYC and talking and power and powerlessness in our city.
