On Monday, Thad Cochran of Mississippi, the ranking Republican on the Appropriations Committee, introduced an amendment to strike the withdrawal language from the supplemental but not the benchmarks and reporting requirements. Trying to strip all three provisions at once raised the prospect of complicating the Republican effort to eliminate the withdrawal goal…

The amendment failed 48-50. The last of these votes went precisely opposite. I guess Trent was wrong:

In a television interview with Fox News on March 25, Minority Whip Trent Lott, R-Miss., said that although GOP leaders had not done a whip check, he thought they had enough votes to strip the Iraq withdrawal provision. In any case, the legislation faces a presidential veto threat.
