PHILADELPHIA (CBS) — Voters in Tuesday’s Pennsylvania primary will select nominees from both parties to replace Attorney General Kathleen Kane. Kane is not seeking re-election as she fights criminal charges in Montgomery County.

The key issue in the race, according to the candidates, is who would be best to restore integrity to the Office of Attorney General.

There are two Republican nominees; long-time state senator John Rafferty and former state and federal prosecutor Joe Peters. Rafferty spent time in the AG’s office in the late 1980’s and early 1990’s and has the backing of the Pennsylvania GOP. Peters bills himself as the outsider, and points to his experience as a cop and a prosecutor.

There are three Democratic candidates; progressive Josh Shapiro, currently Montgomery County Commissioner, conservative pro-life Democrat, Northampton County District Attorney John Morganelli, and Allegheny County District Attorney Stephen Zappala. Morganelli and Zappala have attacked Shapiro, calling him a politician rather than a prosecutor. Shapiro argues he has a record of cleaning up messes, most recently as the Chair of County Commissioners.
