CAMBRIDGE, Mass. — This is what it’s like being Nancy Pelosi:

Republicans are running ads against you again, morphing your face into a monster mask of a big-spending, amnesty-loving San Francisco liberal. Democratic candidates are running from your leadership, declaring it time for a new generation in Washington even as they welcome endorsements from Joe Biden, who’s been around nearly two decades longer.

David Hogg, the chiseled-jaw face of the teenage Parkland shooting survivors, lectured you about Harvey Milk and social activism — “Yes I know; he was my friend” you replied, with your Catholic school manners — and told New York magazine you were “old.”

Now comes a young Harvard man, a graduate student, turning your exhortation on the power of public sentiment back on you — you have just quoted Abraham Lincoln — to ask about the Democrats “running on a platform of not supporting you.”

“How does one deal with this negative public sentiment, and reorganizing your coalition and bringing them back under your leadership and support for you?” he says in front of the standing-room crowd at the John F. Kennedy School of Government here.
