Speaker Nancy Pelosi (D-Calif.) on Thursday expressed optimism that the U.S. will eventually elect a female president, despite it being virtually certain that the 2020 Democratic presidential nominee will be a man after Sen. Elizabeth Warren (D-Mass.) withdrew from the race earlier in the day.

Pelosi acknowledged that it won’t be this year given the likely choice between the major parties of President Trump and either former Vice President Joe Biden or Sen. Bernie Sanders (I-Vt.), but maintained that women are making “progress” following the record number of women elected to the House in 2018 and Hillary Clinton becoming the Democratic nominee four years ago.

“We’ll have a woman president. I know we will. I don’t know who it is quite yet,” Pelosi, the only woman to serve as Speaker to date, said at an event at the Georgetown University Institute of Politics and Public Service moderated by SiriusXM’s Julie Mason.

The Democratic presidential field at one point included six women: Warren, Rep. Tulsi Gabbard (Hawaii), author Marianne Williamson, and Sens. Amy Klobuchar (Minn.), Kirsten Gillibrand (N.Y.) and Kamala Harris (Calif.).

Gabbard is the only female candidate who has still not exited the race, but her candidacy remains a long shot and polls in the single digits.

Pelosi suggested that the size of the primary field may have contributed to the female candidates having difficulty consolidating enough support to break through to the top of the pack.

“This time, the field was so big, the support so spread, perhaps if there hadn’t been so many different candidates then a focus on one or two to begin with … would have been different,” Pelosi said.

“But there were a lot of men who didn’t make the cut either,” Pelosi added.

She suggested that fewer women seem to either promote themselves as potential presidential material or have supporters urging them to run compared to men.

“I haven’t necessarily seen that around women. Hillary, yes,” she said.

She also took the opportunity to give advice to the assembled Georgetown University students in the audience who might consider running for public office themselves.

“Just build your confidence, but also take stock of what you have to offer, whether you’re running for office or running for president.”
