Fred Hiatt makes some good points in his Washington Post column today. He points out that the Democratic focus on trying to weaken the President also undermines the war effort and that effort is too important to be reduced to political manipulation.

Whether Iraqis are in fact committed to a life-or-death struggle for democracy will become clear as its army does, or does not, continue to shoulder a greater burden. But the aptness of Mahdi's view of the United States is already evident in Congress, which pours most of its Iraq-related energy into allegations of manipulated intelligence before the war.

"Those aren't irrelevant questions," says Sen. Joe Lieberman (D-Conn.). "But the more they dominate the public debate, the harder it is to sustain public support for the war."

What Lieberman doesn't say is that many Democrats would view such an outcome as an advantage. Their focus on 2002 is a way to further undercut President Bush, and Bush's war, without taking the risk of offering an alternative strategy -- to satisfy their withdraw-now constituents without being accountable for a withdraw-now position.

Many of them understand that dwindling public support could force the United States into a self-defeating position, and that defeat in Iraq would be disastrous for the United States as well as for Mahdi and his countrymen. But the taste of political blood as Bush weakens, combined with their embarrassment at having supported the war in the first place, seems to override that understanding.

Hiatt is not a cheerleader for Bush; he outlines several lines of criticism that the loyal opposition could be following rather than misleading people about how we got into the war.
