In commenting on the abortion compromise in the Senate health care bill, Senator Barbara Boxer said, "You have both sides criticizing it [the compromise], which means we did what we had to do, we compromised in a fair way."
Let's say an innocent man is put on trial for murder. The prosecution wants him to be found guilty and executed. The defense seeks his acquital and release. The judge wishing to give something to both sides, finds him guilty and gives him 20 years in prison with eligibility for parole after 10. Neither side got everything it wanted. They both complain. But the judge tells the press, "You have both sides criticizing it, which means I did what I had to do, I compromised in a fair way."
