In the later years of her life, Jeanette Rankin took part in anti-Vietnam War protests.
Not long after Rankin (1920), Oklahoma unexpectedly elected the second woman in history to Congress, an anti-abolitionist named Alice Robertson. She only lasted one term, losing reelection in the Democratic landslide of 1922.
I think you meant anti-feminist, not anti-abolitionist. Ms. Robertson was a good Conservative and was born and grew up on the Creek Reservation. I find her more admirable than Rankin (I have her autograph, too, an extremely hard to find signature). Hers was more a fluke win in the ‘20 landslide over the incumbent Democrat, Bill Hastings (which saw the OK delegation go majority GOP, 5R/3D, for the first and last time for three-quarters of a century until 1994 — it would’ve gone 6R/2D had one Rep., John Harreld, fresh off a special election win when the Dem incumbent died, not decided to take a risk and run for the Senate seat, which paid off for him when adjacent 6th district Congressman Scott Ferris took out legendary incumbent Thomas Gore (distant cousin of Al, but closer relative to moonbat writer Gore Vidal) in the Dem primary and failed to unite the party behind him. Harreld became the first GOP Senator from OK).
Hastings took his seat back in ‘22 and Robertson retired to working at a Veterans Hospital. The Muskogee-based OK-2 would not elect a Republican again to this seat until Dr. Tom Coburn in 1994 (and not again since his departure).
