Knowing the Stinky, the paper's motivation may be that they want Hillary installed as a stepping stone to the rat nomination for Prez. Never believe for a second that the Stinky wants anything but what is best for their party. Their intentions are ALWAYS suspect.
I think the Inquirer's editors are kind of good-government freaks, even more than they are liberals. They have done a pretty good job in the two years I have lived in PA of fairly pointing out the slobs and cretins in both parties. Remember, the Inquirer broke the latest story on Bob Menendez that forced him to disassociate himself from his closest political bagman. I expect the paper will endorse Tom Kean, Jr. in that race. They really hammered Jim McGreevey as well. It's kinda nice to see.
