Democrats succeeded in delaying a vote on John Bolton, President Bush's nominee to be America's U.N. ambassador. They now say they will filibuster Bolton's nomination unless the Bush Administration releases long sought after classified documents about Bolton that could effect his nomination. Thus far, the administration has dragged its feet in releasing the documents.

The vote was 56-42, keeping Republicans four votes short of the 60 they need to vote on the Bolton.

Democrats believe that Bolton's abrasive and blunt style is inappropriate for the United Nations while President Bush claims that Bolton's take-no-prisoners approach is just what the U.N. needs.

California Democrat Barbara Boxer was hoping the president would withdraw Bolton's nomination. 'I would hope the president will think about what happened here,' Boxer told reporters. 'I hope cooler heads will prevail and we see a new nominee.'

As of now, Republicans intend to keep fighting for Bolton's nomination and the White House is standing by Bolton. 'What you see here is partisanship, and that is unfortunate,' said Virginia Republican Senator George Allen.

The delayed vote is seen by political analysts as a setback for Senate Majority Leader Bill Frist who remains unable to get the president's more conservative nominees through the Senate.

A frustrated Frist again raised the filibuster issue, seemingly returning to his call for a change in Senate rules. 'John Bolton, the very first issue we turned to, we got what looks to me like a filibuster,' Frist told the Associated Press. 'It certainly sounds like a filibuster … it quacks like a filibuster.'

The documents Democrats are seeking involve Bolton's use of government intelligence information on Syria and on instances when Bolton asked for the names of U.S. officials whose names were secretly picked up by an American spy agency.

There were intense negotiations to reach a compromise on the documents, but they broke down when the administration refused to reveal the names of the officials involved.

Frist is expected to call for another vote on Bolton's nomination soon. The fight over procedural matters concerning the Senate's confirmation of presidential nominees appears to be far from over.
