Since it was first held 32 years ago, the South Carolina Republican primary has been won by the partys most electable candidate, the one backed by the Republican establishment and invariably the winner of the nomination. On Saturday, the state veered in an extreme direction, and the outcome spoke poorly for a party that allowed itself to be manipulated by the lowest form of campaigning.
Newt Gingrich won the primary by a decisive margin of 12.5 percentage points, and there is no mystery about how he did it. Two-thirds of voters interviewed in exit polls said they made their decision on the basis of the two South Carolina debates, where Mr. Gingrich exploited racial resentment and hatred of the news media to connect with furious voters.
