GOP presidential candidate Newt Gingrich was named the projected winner of the South Carolina primary within moments of polls closing in the state Saturday. In the latest sign that the former speaker of the House's large margin of victory was a result of explosive last-minute momentum, exit polls show that many Palmetto State voters hadn't made up their minds until this week.
The Associated Press reports:
A majority of South Carolina Republican voters said they decided on a candidate in the last few days, and they favored Gingrich by a double-digit margin. Santorum and Romney were about even for second among this group.
