In my opinion,
because they think he can beat it. However,
There's lots to worry about with John Bolton other than his complete emotional unfitness as a manager.
The White House has blocked the NSA intercepts and blocks investigation into the allegations of his recent perjury before the Senate Foreign Relations Committee,.
But there's this from Steven C. Clemons of The Washington Note
Bolton promulgated the Niger-Uranium story after intelligence analysts had killed it in the State Department and may have had his staff lie about his role.
Bolton acted without vested authority in issuing the Russians a deadline on the ABM Treaty.
Bolton was accused by Senators Pete Domenici and Peter Fitzgerald of taking his eye off the ball in his current job and not moving quickly or effectively enough to tie up arrangements with Russians on weapons grade nuclear materials.
Additional findings above and beyond abusive behavior (under the fold):
More from The Washington Note:
Bolton has defied Congress on many, many occasions -- refusing to appear, holding back requested witnesses and information, and allegedly destroying Iran-Contra related evidence.
Bolton accepted money from the Taiwanese government for reports which he presented to Congress without indicating the source of said funds. Bolton also helped preside over a significant amount of Taiwanese government money that annually flows into the American Enterprise Institute and demonstrated no compunction about concerns over objectivity and that funding.
Bolton succeeded Michael Baroody as President of Haley Barbour's National Policy Forum which not only took foreign money but acted as an organ of the Republican National Committee to such an overt degree that its non-profit status was stripped.
I don't want this more substantive emphasis to detract from the very real attacks this man has made on his fellow human beings, which I think warrant his removal from consideration. But it's gotten so even the committee Repugs are playing into the probable White House directive to keep talking temperament.
Remember this is a man who saw his first national political duties in the office of notoriously bad VP Spiro T. Agnew.
