She is providing an object lesson, especially to the young, of what happens when the Nation chooses leaders based upon emotionalism, pop-culture, the mood of the moment, and imaginary issues such as AGW, and "torture" of murderous thugs.

Young people can be pretty sharp, and tend to get very analytical, even judgmental of their elders at a certain point. Mrs. Pelosi is providing them with a practical education in unethical political posturing.
On top of that, I have some hope that her political implosion may help to make politics once again uninteresting to the uninformed strata of society.
Finally, she is providing us with much needed comic relief!
