Albuquerque, N.M. ? Sen. Pete Domenici on Thursday withdrew his support of President Bush’s Iraq war policy and embraced a proposal to bring home most troops by March.

The longtime New Mexico senator is the latest of several Republican stalwarts who have abandoned Bush on Iraq in the past 10 days. They have urged a change sooner rather than later and further isolated the GOP president in his attempt to defend the unpopular war.

Last week, Sens. Richard Lugar, R-Ind., and George Voinovich, R-Ohio, said the U.S. should significantly reduce its military presence in Iraq while bolstering diplomatic efforts. Sen. John Warner, R-Va., this month is expected to propose a new approach.

Domenici made his views known Thursday, though he said he has not talked to the administration about a strategy shift.

“I have carefully studied the Iraq situation and believe we cannot continue asking our troops to sacrifice indefinitely while the Iraqi government is not making measurable progress to move its country forward,” he said.

The senator said the situation in Iraq is getting worse. He said he now supports a bipartisan bill that embraces the findings of the independent Iraq Study Group.
