The fact that she was the first woman elected to Congress may be worthy of consideration in itself. But that's not the most relevant milestone of this extraordinary woman's career. She was also a leader in the effort to allow women the right to vote in America.
More controversially, Rankin was the only member of Congress to vote against entry into both World Wars -- an historical footnote of Forrest Gump-esque serendipity. As she defined her lifelong opposition: "War is the slaughter of human beings, temporarily regarded as enemies."
Those votes and the rest of Rankin's career represent the brave, progressive and independent thinking that should win her a ubiquitous place in our wallets. It's also the reason it won't.
The Treasury Department announced this summer that the new $10 bill will enter circulation in 2020, marking the centennial of the 19th Amendment, which gave women the federal right to vote.
Rankin was elected four years earlier than the amendment and is one of the few suffragists (whose goal was to secure that right) to actually hold national office. Even before she was elected, Rankin had a remarkable career as an activist and professional lobbyist, helping to ensure women the right to vote in Washington State in 1910 and Montana in 1914, where she was elected to Congress at age 35.
And once in office she opened the very first House floor debate on a constitutional amendment for women's suffrage. In other words, she was both a pioneer and successful agent for the very milestone the new $10 bill is honoring.
She was also, surprisingly, a Republican, though clearly the GOP has moved away from its progressive roots as she ran on a non-partisan platform of social welfare and a woman's right to vote.
International events, however, immediately interfered with that agenda. Only four days after she was sworn in on April 2, 1917, Congress voted on whether to go to war with Germany. She voted her conscience, joining 49 others against the war resolution. "I want to stand by my country, but I cannot vote for war," she said as she cast her vote.
Fellow suffragists tried to dissuade her, worried the vote would hurt their cause. And the Helena Independent newspaper in her home state referred to her as "a dagger in the hands of the German propagandists" and "a dupe of the Kaiser." When her at-large Congressional seat was eliminated by state gerrymandering a year later and the GOP locked her out of the party, Rankin ran for Senate as an independent and lost.
