As I said before, Smith's defection was in furtherance of an ill-fated presidential quest, which crashed and burned within a month of his quixotic declaration. He gave a wink-and-a-nod after John Chafee died, since he coveted the chairmanship of a committee Chafee headed. Smith's human, just like the rest of us, and threw principle to the wind when it stood to benefit him.
Frankly, ANWAR doesn't do anything for me. It is not even on most conservative's radar screen whereas Sununu's consistent support for increased illegal immigration and support of Palestinian and other Islamicist terrorist groups IS.
You slur Sunnunu as a terrorist supporter with no, or anecdotal, evidence, where I can point to ANWR as a further lessening of US support on foreign oil, with the evidence that Smith is against exploration there.
Smith's going down, one way or another.
