The New Delegate Leader: Newt Gingrich
Newt Gingrich will win the 11 statewide delegates and two each from the five congressional districts he appears to be winning handily.
(The results by county can be found here; the new U.S. House district map can be found here.)
There are two patches where Romney is doing well; most of the map is Gingrich territory.
Worst-case scenario for Gingrich is he wins 21 delegates and Romney wins 4 delegates. The best-case scenario is that he wins all 25.
UPDATE: It now appears that Gingrich will sweep all seven of South Carolina’s congressional districts, putting all 25 at stake tonight into his pile.
