A chance for Obama to serve the country and himself

A lot of people are speculating that in response to the tragic shooting at Rep. Gabrielle Giffords' event over the weekend, President Obama should or will react like President Bill Clinton did in response to the Oklahoma City Bombing, and blame the far-right, and by implication, the right. I think he should take a different page from Clinton's book. I think this could be Obama's Sister Souljah moment, and he could use it to help the nation and his own political stature at the same time.
