Let us sing a song about the wonderfulness of Nancy Pelosi.

What a run she’s been on. This week — with the big financial reform package edging toward completion, and the House approving a major campaign finance reform bill — was a reminder of what an incredibly productive speaker she’s become.

Last winter, when Washington was backing away from the whole health care deal after the Republicans won Ted Kennedy’s Senate seat, Pelosi was uncowed. “We’ll go through the gate. If the gate’s closed, we’ll go over the fence. If the fence is too high, we’ll pole vault in,” she said. “If that doesn’t work, we’ll parachute in. But we’re going to get health care reform passed for the American people.”

I sort of like the image of Nancy Pelosi parachuting in. Would she wear her high heels? Probably not, but her hair would still look as if it had been blow-dried by a stylist on the way out of the airplane.

She’s a 70-year-old perpetual motion machine who seems, in her public appearances, both ultra-programmed and ultra-intense. Many Americans were first introduced to her when the new speaker sat behind President Bush at his State of the Union speech in 2007, blinking so ferociously that she seemed to be sending out Morse code distress calls from the back of the podium.

In conversation, she’s a runaway train. Talking about global warming in an interview last week, she warned: “You don’t want me to go into the melting of the polar cap and the glaciers and the great rivers of Southeast Asia and the water supply in Tibet and the encroachment of the Gobi Desert and the sandstorms in Beijing and the rise of sea level in all of our maritime areas in the world and. … I would just recommend you go to Alaska to see what is happening.”

The Republicans have turned Pelosi into the Demon Grandmother — in ads, a satanic figure in the flames of deficit spending, or a 50-foot monster smashing houses with her big-government feet. (She seems utterly indifferent to the endless public pummeling — although she did express some dismay, in an interview with The Times’s Mark Leibovich, that people had been speculating that she might have had a face-lift.)

But even the public that likes the legislation she’s been churning out tends to underestimate her.

Maybe that’s because she came up through the ranks of the California Democratic Party, and then the House, with a reputation as a prodigious fund-raiser. It’s an idea Pelosi herself isn’t comfortable with. She rejects the description of her early party-building activities as being about raising money. “I wasn’t a fund-raiser. I was like a small businesswoman,” she protested.
