Candidates endorsed by the Sierra Club in the May 2009 primary election were all successful in the November 3 general election. The slate of three reform-minded candidates endorsed by the Sierra Club all won seats in the Monroeville municipal election: Diane Allison (D-R), Lois Drumheller (D-R) and Bernhard Erb (R).
