9 historic firsts in the U.S. midterm elections

Two years after Donald Trump was elected president of the U.S., the midterm elections ushered in a wave of historic firsts for marginalized and minority groups.

The midterms saw the Democrats retake the House of Representatives, and the Republicans gain ground in the Senate. Gubernatorial races were also up for grabs.

Voters also elected a diverse group of people, many of whom made history as the first person of their race, gender or sexual orientation in their respective races.

Here’s a roundup of all the historic firsts the U.S. saw Tuesday night:

Texas sends first Hispanic women to Congress

Veronica Escobar and Sylvia Garcia (both Democrats) will head to the House of Representatives to represent Texas.

While Hispanic men have been elected, it’s a first for Hispanic women. Texas’ Hispanic population has been on the rise, and it’s expected the community will be the largest population growth by 2022, according to the Texas Tribune.

First female governors in South Dakota and Maine

Kristi Noem and Janet Mills are the first women to win gubernatorial races in South Dakota and Maine, respectively.

Before this election, 22 states had never elected a woman as governor, but that number is now down to 20. States including New York and California are among the 20 who have never elected female governors.

Record-breaking number of women running and elected

Women previously held 84 out of 435 House seats, which was a record.

But as of Wednesday morning, the record was on track to be broken as the final results are still rolling in.
