If Sharice Davids prevails in November, she would represent several firsts in Congress.

She would be the first lesbian congresswoman from Kansas.

She would be one of the first Native American women in Congress. (Deb Haaland, who won the Democratic primary in June in a blue district in New Mexico, could also be elected in November.)

And she would be the first congresswoman who was once a professional mixed martial arts fighter.

Ms. Davids became the Democratic nominee in the Third Congressional District in Kansas on Wednesday, according to The Associated Press. That sets her up against Representative Kevin Yoder, a Republican who has served since 2011.
