Hewitt is the consummate politician. He has made his principled stand against absorbing all these illiterate, dependent, illegal Immigrants, but believing he is on the losing side of this issue, is casting about for cover for leaving this popular, but ultimately losing fight behind. Being a politician, he knows, like Hillary, he doesn't have to win all battles; it is the perception that counts and folks will remember he was for it before he was against it, or better still, before he was deceived into cutting the opposition too much slack! BUT HIS MOTIVES WERE PURE!
Translation: Hewitt wants to move on to another issue! There is no glory to be had in this one. It is more like, "when did you stop beating your wife?"
