Not once during his lengthy and moving eulogy in Tucson, Arizona, at the memorial service for those whose lives were cut short by gunman Jared Loughner, not once in his many references to Christina-Taylor Green, the nine-year-old girl who tragically died alongside five others, did President Barack Obama mention his own daughters, Sasha (also 9) and Malia (12). But we all knew what he was thinking. That’s restraint. That’s class. Last night, he embraced us all, and we were all his children.
