Lisa Blunt Rochester runs for Senate in Delaware.

Democratic Rep. Lisa Blunt Rochester, the first woman and first Black person to represent Delaware in Congress, has announced her candidacy for the state's open Senate seat. If elected, she would be the first Black senator to represent Delaware. Blunt Rochester is widely viewed as a front-runner for her party's nomination for the safe Democratic seat. Her candidacy underscores the lack of diversity in the Senate, which has had no Black female members since Kamala Harris left the chamber to serve as vice president.
