I think Congress, the President, the world should not be involved with this poor lady's life/death choice. It is a family matter. The husband has spoken. The parents have lost. Let this lady go.
It is ludicrous that a country's' government should be involved in the life and death of people. Leave that to the wars. Let people decide for themselves how they wish to live and die. Government has overstepped it's bounds once again.
Rest In Peace Mrs. Schiavo.
