No plot, as far as I can see. Just an attempt by several media sources to confuse the issue and turn that twisted form of the issue into a club to beat good conservatives with.
As far as I’m concerned, there are only two people involved in this issue that matter: Bachmann, for her statements on Gardasil itself and how it might feed anti-vaccine hysteria, and Perry, whose use of the EO process to mandate the treatment was far enough outside of normal “channels” that it warrants a closer look.
Yes, a plot. A plot! A plot, I tell you!
