SOUTH BEND (AP) -- Tea party conservatives who helped Republicans gain two Indiana U.S. House seats two years ago are showing their dissatisfaction with Washington by challenging some of the candidates they helped elect.
Freshman Reps. Jackie Walorski in the 2nd District and Susan Brooks in the 5th both face strong tea party candidates in Tuesday's primary. Second-term Rep. Larry Bucshon in southern Indiana's 8th District also faces a challenge from the right.

All three have drawn criticism for not being conservative enough. Walorski and Brooks received the lowest ratings among Indiana's delegation from the Club for Growth earlier this year.
All nine congressional incumbents are on the ballot. Only longtime Democratic Rep. Pete Visclosky is unopposed.
