Heres the deal, Lieberman knew he was making statements and expressing opinions deeply contary to his affiliated parties touted official position. To suggest that Lieberman would not have approved the admins use of his comments is, I think, disingenuous to say the least.
The bush admin was absolutely justified in using the senators comments in their own defense. I suspect that Lieberman might have a hellbetter chance in the next election because of his stance on Iraq.
Iraq is likely going to prove to be a very smart move, albeit a complicated and difficult move, in the future of the middle east and the world. To have bucked his parties position and instead, made the right move, will really give Lieberman a strong advantage going against his parties dogma ladden contenders. Even Hillary seems to sense this, although she is too heavily influenced by the anticons to be of much use to anyone now.
