Cori Bush is now the first Black woman elected to Congress in Missouri.

The Democrat, who ran on a progressive platform, won in a landslide over Republican contender Anthony Rogers with nearly 79 percent of the vote from Missouri's 1st congressional district, as reported by The Associated Press.

Bush's win in the general election comes after a tough Democratic primary this past August, in which she beat incumbent Lacy Clay, the establishment Democrat and longtime representative who took over the post from his own father (and who received an endorsement from California senator Kamala Harris). In contrast, Bush first made a name for herself as a local activist following the 2014 Black Lives Matter protests in Ferguson, where Mike Brown was killed by a police officer.

"I fight because I know what it's like to live paycheck to paycheck, to be burdened with student and medical debt, and to live day to day in St. Louis where poverty is violence, crime is rampant, and our unhoused community grows daily," Bush said in a statement on her website. "We need a champion for policies that will affect residents of Missouri’s 1st directly. I AM that champion. I'm running because you deserve better. I am running because I am the people I serve.”

Following her win, Bush posted a photo of herself posing in front of a portrait of Shirley Chisholm, the first Black woman to vie for the Democratic Party's presidential nomination and the first Black presidential candidate for either party. "The First," Bush captioned the symbolic picture.

In a Twitter thread, Bush wrote of her historic win, "Mike Brown was murdered 2,278 days ago. We took to the streets for more than 400 days in protest. Today, we take this fight for Black Lives from the streets of Ferguson to the halls of Congress. We will get justice."

She also paid homage again to Chisholm, writing, "Shirley Chisholm became the first Black woman elected to Congress 52 years ago. Today, I became the first Black woman elected to represent Missouri in Congress. It's 2020. I shouldn't be the first, but I am honored to carry this responsibility."

She ended the thread by reflecting on the revolutionary moment of this election. "To all the counted outs, the forgotten abouts, the marginalized, and the pushed asides. This is our moment," she wrote. "We came together to end a 52-year family dynasty. That's how we build the political revolution."
