Gingrich bashing has a long history. I've even done a little myself (last May, after he dissed Ryan's plan). On the other hand, Cain and Cain-bashing are relatively new developments. We'll need to see how it shakes out.
FWIW, I voted Cain / Gingrich. Truth be told, I'll take anyone who can beat Obama. Even Huntsman (but hopefully, I'll not be reduced to voting for the MittWitt!).
A year ago here, you couldn’t find anybody here saying anything positive about Newt.
