"Global Warming" is a fraudulent issue designed to justify government controlled economy and money-laundering in the form of "carbon credit trading". Its also a perfect litmus test which exposes the corrupt, the obtuse, and most importantly the unqualified-to-be-president.
I agree with you that in this exchange Giuliani, Huckabee, and McCain stand exposed and disqualified. Romney teeters on the brink, saved from himself by Thompson.
Not so. If you view the video you will see that Mitt raised his hand higher then Huckabee at one point. He too stands exposed. There was no teetering.
