Nancy Pelosi proved to be a moving target.
When I began working on a biography of the House speaker two years ago, the deadline to my publisher was Labor Day 2020, with an extension carved out to submit a final chapter right after Election Day. The theory: Early in the election year Pelosi would be supplanted as the leading Democratic counterpart to President Donald Trump by the party’s presidential nominee, whoever that turned out to be. That would leave time and space to assess the most powerful woman in American history. Then election night would settle Trump’s future and the success of Pelosi’s stand against him.
