The newest GOP buzzword: anguished. That’s the phrase most often used these days to describe how Republicans feel about the war in Iraq. Three prominent GOP Senators have rhetorically broken with the Bush Administration in the past two weeks. More are sure to follow.

According to the New York Times, "White House officials fear that the last pillars of political support among Senate Republicans for President Bush’s Iraq strategy are collapsing around them." Maine Senator Olympia Snowe says enough is enough. She invokes another Iraq buzzword: benchmarks. The Iraqi government must meet the targets requested by Congress by much-vaunted September. Or else.

Yet another dissident Senator, Indiana’s Richard Lugar, says "there’s no conceivable way that" the benchmarks will be met. And the White House may be preparing to scrap those goals altogether in search of "alternative evidence of progress."

What’s an anguished Republican to do? They’ll be votes on Iraq in Congress this week. That’s a good place to start.
