Just out from SEIU's Andy Stern ...

It's clear to us that the right-wing conservatives in control of the leadership of the Republican party in Pennsylvania left Senator Specter long ago and we are pleased that he has decided to do the same. Just as he did with his leadership on the economic stimulus bill, Senator Specter has once again demonstrated the political courage it takes to put the interests of the working families of Pennsylvania ahead of partisanship. We have always had tremendous common ground with Senator Specter on issues important to working families including the need for reform to our nation's labor laws. We look forward to continuing our long history of working with Senator Specter to create positive change for the working families of Pennsylvania.

Late Update: Here's the post at the SEIU blog.
