Senate Democrats have once again blocked the confirmation of John Bolton, President Bush’s controversial pick for UN ambassador. Last night, Republicans failed for the second time to force a vote. The motion to close off debate fell six votes short of the three-fifths majority of 60 required for cloture. The vote was 54-38 — largely along party lines. But there is concern that Bush may try and get Bolton in through a back door. The White House has not ruled out the possibility of sidestepping the Senate by naming Bolton as UN ambassador in a recess appointment. If that happened, Bolton would get an 18-month stint that would not require Senate approval. White House spokesman Scott McClellan said “It is critical that we get him in place.” This came after Secretary of State Condoleezza Rice hinted on Sunday that Bush may install Bolton through a temporary recess appointment. She told FOX News “We’ll see what happens this week.”
