DOVER, Del. (AP) — U.S. Rep. Lisa Blunt Rochester will become the first woman and first Black person to represent Delaware in the U.S. Senate. And when she does, she’ll join Democrat Angela Alsobrooks from Maryland, who also won a U.S. Senate seat Tuesday. Together they will become only the fourth and fifth Black women to serve in the chamber. Blunt Rochester defeated Republican Eric Hansen on Tuesday to fill the seat left vacant by fellow Democrat Tom Carper. Carper handpicked Blunt Rochester as his preferred successor when he announced his retirement last year. Blunt Rochester has served four terms as Delaware’s lone representative in the U.S. House.
