Assuming that the President does indeed veto the bill, there will be lots of things to say about this between now and the override votes.  I doubt, though, that any of those things will be more eloquent or powerful than this Open Letter to President Bush from Rev. Jim Wallis at Sojourners.  

Wallis reflects on a meeting about poverty with then-President Elect Bush in an Austin church. He writes of that meeting: “You asked us questions. One was, ‘How do I speak to the soul of America?’ I remember answering that one by saying to focus on the children. Their plight is our shame and their promise is our future. Reach them and you reach our soul. You nodded in agreement.” 

Wallis concludes:

 How have your priorities stayed so far from those children, whom you once agreed were so central to the soul of the nation? What do they need to do to get your attention again? You will be literally barraged by the religious community across the political spectrum this week, imploring you not to veto children's health care. I would just ask you to take your mind back to a little meeting in a Baptist Sunday school classroom, not far away from where you grew up. Remember that day, what we all talked about, what was on your heart, and how much hope there was in the room. Mr. President, recall that day, take a breath, and say a prayer before you decide to turn away from the children who are so important to our nation's soul and to yours.
