The glass ceiling that Sen. Kamala Harris just broke when she became the first woman ever to be elected vice president of the United States may not be the highest in American politics, but it's as close as they come. Harris also has the distinction of being the first Black and the first Indian American vice president-elect.

President Donald Trump is disputing the results, which are still being litigated in court. Nevertheless, electoral politics have almost certainly been changed forever, a mere 100 years after the 19th Amendment guaranteed women an equal place in the voting booth.

"I can't imagine on the Democratic side ever seeing another ticket that is two white men," says Debbie Walsh, the director of the Center for American Women and Politics at Rutgers University.

In some ways, this moment seemed inevitable. Look at the unprecedented number of women — six, including Harris — who ran as Democrats for president this election cycle. A woman was the Democratic nominee for president four years ago. Female voters — particularly Black female voters — are essential to Democratic victories. Why wouldn't there be a Black female running mate?

Well, here's why: We are not in a post-sexist society — not any more than we were in a post-racial society in 2009 when President Barack Obama entered the White House or in 2017 when he left it. So, the elevation of Harris, 56, is a profoundly big deal. It's made even bigger by the fact that Biden will be the oldest man — at 78 — to become president. If he doesn't seek a second term, Harris will occupy the pole position in the race to replace him.

Harris is part of a tiny sorority of women — three — who have even been nominated for vice president by a major party.

The first was Rep. Geraldine A. Ferraro, D-N.Y., a former Queens prosecutor plucked from relative obscurity in the House. Pressured by women's advocates and believing there was a gender gap to fill, former Vice President Walter Mondale picked Ferraro as his running mate to try to spark his struggling campaign in 1984. Incumbent Ronald Reagan beat them in a landslide. Ferraro died in 2011.

The second was Sarah Palin, the little-known first-term Republican governor of Alaska. Sen. John McCain, R-Ariz., made the admittedly unorthodox pick of Palin to be his running mate in 2008 in the hope of trimming Obama's lead in the polls. But the choice backfired after Palin's inexperience showed through in interviews and on the debate stage, and Obama won easily.

It's a reminder of the rarity of female vice presidential candidates that Palin, the polar opposite of Harris in politics and beliefs, took to Instagram to offer some friendly, nonpartisan advice after Biden announced her selection.

"Climb upon Geraldine Ferraro's and my shoulders, and from the most amazing view in your life consider lessons we learned," Palin wrote. Among those lessons: "[D]on't get muzzled."

It's difficult to believe that Harris, a former San Francisco district attorney and California attorney general who made a reputation in the Senate for asking tough questions, would ever let anyone do that.

Witness how she stopped Vice President Mike Pence from talking over her during their debate; that alone makes her a role model for women young and old.
