Viva, Killer Amendment.
An attempted killer amendment? By that master of tactics from the great state of OK?
Jeff Jenkins wrote a great paper (and put my name on it, too) about killer amendments, in the JOP in 2003. We laid out some conditions under which an amendment might be "killer," and those conditions are pretty restrictive.
On the other hand, my friend Gerry Mackie is skeptical.
