I think it certainly is an ADIZ argument. Boyer has (disingenously, of
course) argued that the ADIZ is unnecessary largely because of the minimal
threat posed by light aircraft ("I fly a C-150: fear me"). Now, we all
know that jets and big turboprops also fly GA.

Personally, from what I know, I would think that small aircraft like most
Cessnas and Pipers s/b exempted from the ADIZ. But this gets difficult
politically: AOPA would then be standing against the biz jet owners. A
unified front is preferable. But if this thing gets traction (as I
stongly suspect it will, if not a foregone conclusion), Boyer may decide
to change tactics.
