This week’s Democratic primaries in Kentucky, New York, and Virginia saw a number of progressive challengers defeating moderate or establishment rivals. Of particular note were the victories of two insurgent candidates in New York: Jamaal Bowman, who defeated 16-term incumbent Eliot Engel, and Mondaire Jones, who triumphed over a crowded field in the 17th District to become one of the first openly gay black men ever elected to Congress. Jones joins Mehdi Hasan to discuss his victory.
