This might not mean a thing and then again, it might. 
From Mercury News:
CHARLESTON, S.C.—Newt Gingrich has cancelled a campaign appearance in South Carolina because of poor attendance.
The Republican presidential candidate was scheduled to speak to the Southern Republican Leadership on Friday. But a campaign spokesman told reporters that he would no longer be appearing due to poor attendance.
There were just a few dozen people in the audience at the College of Charleston’s arena, where the event was taking place. The conference has suffered from low attendance all week but Gingrich rival Rick Santorum went ahead and addressed the group on Thursday.
Interesting….very interesting. I wonder if it related these items here? It is to wonder.
