Jacob Weisberg at slate.com thinks the Lamont victory is a disaster for Democrats. This is significant because Weisberg is no Rove-bot. Money quotes:
The problem for the Democrats is that the anti-Lieberman insurgents go far beyond simply opposing Bushs faulty rationale for the war, his dishonest argumentation for it, and his incompetent execution of it. Many of them appear not to take the wider, global battle against Islamic fanaticism seriously. . .
We know this because we have been here before. The Lamont-Lieberman battle was filled with echoes and parallels from the Vietnam era. Democratic reformers and anti-establishment insurgents werent wrong about that conflict, either. Vietnam was a terrible mistake for the United States. But like Iraq, Vietnam was a badly chosen battlefield in a larger conflict with totalitarianism that America had no choice but to pursue. In turning viciously on stalwarts of the Cold War era like Lyndon B. Johnson, Hubert Humphrey, and Scoop Jackson, anti-war insurgents called into question the Democratic Partys underlying commitment to challenging Communist expansion.
