Will George W. Bush's decision to seek congressional approval for invading Iraq slow down the war juggernaut? Up to now, Democrats have only been willing to declare, as Sen. Russ Feingold (D-Wis.) observed after President Bush's Sept. 4 address to congressional leaders, that "To date, the administration has not made the case for military action in Iraq." Even so, these voices have yet to swell into a chorus of serious opposition. Bush seems to be gambling that a month of hearings, ultimately, will produce more support than dissent.
