Mr. Lieberman is not just a senator who works well with members of the other party. And there is a reason that while other Democrats supported the war, he has become the only target. In his effort to appear above the partisan fray, he has become one of the Bush administration's most useful allies as the president tries to turn the war on terror into an excuse for radical changes in how this country operates.
Citing national security, Mr. Bush continually tries to undermine restraints on the executive branch: the system of checks and balances, international accords on the treatment of prisoners, the nation's longtime principles of justice. His administration has depicted any questions or criticism of his policies as giving aid and comfort to the terrorists. And Mr. Lieberman has helped that effort. He once denounced Democrats who were "more focused on how President Bush took America into the war in Iraq" than on supporting the war's progress.
At this moment, with a Republican president intent on drastically expanding his powers with the support of the Republican House and Senate, it is critical that the minority party serve as a responsible, but vigorous, watchdog. That does not require shrillness or absolutism. But this is no time for a man with Mr. Lieberman's ability to command Republicans' attention to become their enabler, and embrace a role as the president's defender. [...]
Mr. Lamont, a wealthy businessman from Greenwich, seems smart and moderate, and he showed spine in challenging the senator while other Democrats groused privately. He does not have his opponent's grasp of policy yet. But this primary is not about Mr. Lieberman's legislative record. Instead it has become a referendum on his warped version of bipartisanship, in which the never-ending war on terror becomes an excuse for silence and inaction. We endorse Ned Lamont in the Democratic primary for Senate in Connecticut.
Supporting Ned Lamont is the only responsible course.
