Allegheny County DA Stephen Zappala scored a major endorsement over the President’s Day weekend.

Lieutenant Governor Mike Stack announced that he will be backing Zappala’s campaign for Attorney General.

“As Lieutenant Governor and a Philadelphia Democratic leader with many years of political history, I can say rarely in public life do we have the opportunity to support a candidate so perfectly prepared for a public office as Allegheny County District Attorney Stephen Zappala is for Pennsylvania Attorney General,” Stack stated in an email to supporters.

“Steve has earned my support and I encourage you to give him yours.”

The endorsement is particularly noteworthy because it appeared Shapiro had the support of the biggest names in the PA Democratic Party. For example, former Governor Ed Rendell is with Zappala’s opponent Josh Shapiro while Gov. Wolf named the Montgomery County Commissioner as the Chair of the Pennsylvania Commission on Crime and Delinquency.

Lt. Governor Stack is not only the highest ranking official to back Zappala, but is also a major Philly politician at a time when both candidates are trying to avoid an east/west divide in this race.

Also running for the Democratic nomination is John Morganelli, while Kane is still toying with a run for re-election.
