Atrios quotes Frank Rich talking about how Sen John Warner (R-VA) will finally break the Republican ice on the Iraq war:

As General Odom says, the endgame will start “when a senior senator from the president’s party says no,” much as William Fulbright did to L.B.J. during Vietnam.

Just as an historical note, though, while Fulbright started speaking out against the war in 1966, US combat troops didn’t leave for another seven years, and LBJ was out of office for five of those years. That’s one hell of an “endgame”.
