Needed: A Copy Editor Who Can Subtract

I just read this on Yahoo! News:
A Public Policy Polling survey released Thursday found that Gingrich's favorable rating with GOP voters has dropped 27 points in the last month--from 52 percent to 38 percent.

By my calculation, 52 - 38 = 14, not 27.

True, 14 is 27 percent of 52, so you could say Gingrich's support among GOP voters has dropped by 27 percent, but not by 27 points. There's a difference.
