In the next few weeks, we're going to hear a lot about the so-called "eleventh commandment" of the Republican party — "Thou shalt not speak ill of another Republican." As Kitty Bennett notes, Ronald Reagan is usually credited as authoring said amendment but someone else did and he just repeated it.
The reason we're about to hear a lot about it is because Mitt Romney's opponents — especially Newt Gingrich — will be ramping up their breakage of that commandment between now and the South Carolina primary on January 21. It'll get ugly, real ugly, and the folks who'll be producing Barack Obama's campaign ads will be sitting and taking notes.
