House Speaker Nancy Pelosi was in a determinedly good mood when she sat down to lunch with reporters yesterday. She entered the room beaming and, over the course of an hour, smiled no fewer than 31 times and got off at least 23 laughs.

But her spirits soured instantly when somebody asked about the anger of the Democratic "base" over her failure to end the war in Iraq.

"Look," she said, the chicken breast on her plate untouched. "I had, for five months, people sitting outside my home, going into my garden in San Francisco, angering neighbors, hanging their clothes from trees, building all kinds of things -- Buddhas? I don't know what they were -- couches, sofas, chairs, permanent living facilities on my front sidewalk."

Unsmilingly, she continued: "If they were poor and they were sleeping on my sidewalk, they would be arrested for loitering, but because they have 'Impeach Bush' across their chest, it's the First Amendment."

Though opposed to the war herself, Pelosi has for months been a target of an antiwar movement that believes she hasn't done enough. Cindy Sheehan has announced a symbolic challenge to Pelosi in California's 8th Congressional District. And the speaker is seething.

"We have to make responsible decisions in the Congress that are not driven by the dissatisfaction of anybody who wants the war to end tomorrow," Pelosi told the gathering at the Sofitel, arranged by the Christian Science Monitor. Though crediting activists for their "passion," Pelosi called it "a waste of time" for them to target Democrats. "They are advocates," she said. "We are leaders."
