Well, given your silence on the lack of enforcement provisions, you are basically saying that the Kyl/Cornyn proposal isn't worth the paper on which it's written.
If defending it was a worthwhile endeavor, you would be doing so with as much vigor as you've shown for attacking a 1972 Charlie Daniels song.
Or your defending a Charlie Daniels article in 2006.(BTW Charlie Daniels never had to got through the scrunity of a political campaign as he collects royalities from his hollyweird stereotype anti-Southern song "Uneasy Rider").
