Sheryl Sandberg for president?

Facebook Chief Operating Officer Sheryl Sandberg is preparing a robust tour in conjunction with her foundation activities this spring to promote her upcoming book, “Option B,” leading some Democratic operatives to speculate that she’s mulling a 2020 presidential campaign.

In recent weeks, her staff interviewed young aides with campaign chops for the months-long project, according to a source familiar with the planning. Another called it “common knowledge” in Democratic Party circles that she is considering such a run.

“Option B” is not, by itself, a political platform from which to launch a presidential bid. It will not outline her worldview or serve as a compendium of positions on domestic issues. Rather, it is a personal book about grief and healing, describing what she experienced after the 2015 death of her husband, philanthropist and Silicon Valley CEO Dave Goldberg. Sandberg is working on the book with high-profile Wharton management professor Adam Grant.

But Sandberg admirers hope “Option B” will provide an object lesson for the millions of women coping with their grief after the election loss by the first would-be woman president and the now-imperiled causes she would have pursued.
