Redistricting: Keough Vs. Broadsword?

It took a bit to sort out the data, but here’s the effect on incumbents of L-71, the North Idaho compromise plan for legislative districts 1-7: Sens. Shawn Keough, R-Sandpoint, and Joyce Broadsword, R-Sagle, would end up in the same district, forcing a face-off in the GOP primary if they both want to keep the seat. In the proposed new District 2, there would be three incumbent state representatives vying for two seats: Reps. Phil Hart, R-Athol; Vito Barbieri, R-Dalton Gardens; and Marge Chadderdon, R-Coeur d’Alene. In the proposed new District 5, there would be four incumbents vying for two House seats: Reps. Tom Trail, R-Moscow; Shirley Ringo, D-Moscow; Dick Harwood, R-St. Maries; and Shannon McMillan, R-Silverton/ Betsy Russell ,  Eye On Boise.
