It’s going to be a blistering weekend throughout the Keystone State but Attorney General candidate Stephen Zappala has a plan.

The campaign is holding a get-together Friday night at the Dog & Pony Restaurant.

The most intriguing detail, though, is the hosts of the event.

Senate Minority Leader Jay Costa, House Minority Leader Frank Dermody and Allegheny County Executive Rich Fitzgerald will all be in attendance as hosts.

All three are from Pittsburgh, as is Allegheny County DA Zappala, and this event further suggests that western PA is coalescing around Zappala’s candidacy.

Just yesterday, Pittsburgh attorney Dave Fawcett dropped out of the race in part to prevent a split of the west’s vote. That news caused a chain reaction which lead to Jack Stollsteimer leaving the race and endorsing Shapiro while John Morganelli touted his own endorsements.

While a regional battle begins to take shape, it is currently unclear what role, if any, incumbent Kathleen Kane will play in this year’s election.
