In one-party states, turnover is rare. So when Dick Durbin gives up the Senate seat he's held since 1997, we'd expect some movement. And, wow oh wow, are ambitious Illinis on the move! To introduce us to the ensemble casts crowding up key races, Henry sits down with Cook Political Report's Erin Covey. 

Henry also explains the Iron Law of Primaries and digs further into early findings on public attitudes about the war in Iran. Plus, we have competing ads from the Illinois Senate race, along with an attack ad against Thomas Massie that indicates midterm party priorities. (And we're flagging an innovative ad featuring Bobby Rush that uses artificial intelligence to boost his endorsement of Jesse Jackson Jr.)
