Somebody's gone to the library

And actually read the Constitution:

WASHINGTON (AP) -- A Senate Republican on Tuesday directly challenged President Bush's declaration that "I am the decision-maker" on issues of war.

"I would suggest respectfully to the president that he is not the sole decider," Sen. Arlen Specter, R-Pa., said during a hearing on Congress' war powers amid an increasingly harsh debate over Iraq war policy. "The decider is a shared and joint responsibility," Specter said.

The question of whether to use its power over the government's purse strings to force an end to the war in Iraq, and under what conditions, is among the issues faced by the newly empowered Democratic majority in Congress, and even some of the president's political allies as well.

"The Constitution makes Congress a coequal branch of government. It's time we start acting like it," said Sen. Russell Feingold, D-Wis., who is chairing a hearing Tuesday on Congress' war powers and forwarding legislation to eventually prohibit funding for the deployment of troops to Iraq.

His proposal, like many others designed to force an end to U.S. involvement in the bloody conflict, is far from having enough support even to come up for a vote on the Senate floor.

Closer to that threshold is a nonbinding resolution declaring that Bush's proposal to send 21,500 more troops to Baghdad and Anbar province is "not in the national interest." The Senate could take up that measure early next month.

But some senators, complaining that the resolution is symbolic, are forwarding tougher bills.

Update: Glenn Greenwald lists a few quotes from Republicans when they were protesting Clinton maintaining troops into Somalia, and declaring that Congress had such the right to remove them.

When Bill Clinton was President, most of the country's leading Republicans did not seem to have any problem at all with Congressional "interference" in the President's decisions to deploy troops (really to maintain troop deployments, since President Bush 41 first deployed in Somalia). There wasn't any talk back then (at least from them) about the burden of "535 Commanders-in-Chief" or "Congressional incursions" into the President's constitutional warmaking authority. They debated restrictions that ought to be legislatively imposed on President Clinton's military deployments and then imposed them.

And Sen. McCain in particular made arguments in favor of Congressionally-mandated withdraw that are patently applicable to Iraq today. And he specifically argued with regard to forcible troop withdrawal that "responsibilities for that lie with the Congress of the United States." The Constitution hasn't changed since 1993, so I wonder what has prompted such a fundamental shift in Republican views on the proper role of Congressional war powers.
