Some days when I hear the latest news report of the Republican presidential primary season, I feel like screaming and tearing my hair out. Is this the best way we can manage to winnow the field to choose our leaders -- constantly making every effort to demonize the opposition, distort his (it's seldom a "her") stated positions, and pour gasoline on the national fires of paranoia? Any seven-year old could tell you that it doesn't raise you up to tear someone else down.
