The Aug. 12 Battle for the Ballot article “The Black sorority that faced racism in the suffrage movement but refused to walk away” was timely, given the naming of Sen. Kamala D. Harris (Calif.) as the Democratic Party’s vice-presidential candidate. At Howard University, Ms. Harris joined Alpha Kappa Alpha. The article noted that sisters of Delta Sigma Theta, one of the country’s first Black sororities, founded at Howard, advocated suffrage despite racist attacks. The efforts of Black women in American politics have consistently held this country to its highest promises.

But just as African American contributions are erased, those of Asian Americans are often made invisible. In 1912, 16-year-old Chinese immigrant Mabel Lee helped lead 10,000 marchers for women’s suffrage in New York and organized the Chinese American community for support. Until its repeal in 1943, the Chinese Exclusion Act banned Chinese immigration and citizenship, but Lee remained steadfast, knowing that transformation follows when women wield power. And for Black women, the right to vote was and still is a fight in many places.

Key roles played by Black and Asian women in women’s suffrage helped ensure ratification of the 19th Amendment 100 years ago this month. Those efforts culminate in this historic moment when a biracial (Black and Asian) sorority woman is now a major party’s vice-presidential candidate. Coincidence? No chance.
