"If there's a child on the South Side of Chicago who can't read, that matters to me, even if it's not my child. If there's a senior citizen somewhere who can't pay for their prescription and has to choose between medicine and the rent, that makes my life poorer, even if it's not my grandparent. If there's an Arab-American family being rounded up without benefit of an attorney or due process, that threatens my civil liberties.
It is that fundamental belief---it is that fundamental belief---I am my brother's keeper---that makes this country work."
Barack Obama, last night at the Democratic Convention. You owe it to yourself to read the entire transcript of his speech.
