In an unusual move, Congressman Raul Labrador has endorsed the legislative candidacies of incumbent Reps. Kathy Sims, R-Coeur d'Alene, and Donald Cheatham, R-Post Falls. In an article published in the Press, Labrador lauded Cheatham as "one of the most reliable, conservative voices in the Idaho Legislature." And Sims as "a tireless advocate of conservative principles during her time in the Idaho Legislature."

Question: Why do you suppose Congressman Labrador took the time to endorse these 2 candidates?
